  • 63509beaf   drivers/memstick/host/rtsx_pci_ms.c: fix ms card data transfer bug ... Browse Code »

    This patch is used to add support for ms card. The main difference
    between ms card and mspro card is long data transfer mode. mspro card
    can use auto mode DMA for long data transfer, but ms can not use this
    mode, it should use normal mode DMA.

    The memstick core added support for ms card, but the original driver will
    make ms card fail at initialization, because it uses auto mode DMA. This
    patch makes the ms card work properly.

  • a0e5a12fd   drivers/memstick/core/ms_block.c: fix unreachable state in h_msb_read_page() ... Browse Code »

    In h_msb_read_page() in ms_block.c, flow never reaches case
    MSB_RP_RECIVE_STATUS_REG. This causes error when MEMSTICK_INT_ERR is
    encountered and status error bits are going to be examined, but the status
    will never be copied back.

    Fix it by transitioning to MSB_RP_RECIVE_STATUS_REG right after
    MSB_RP_SEND_READ_STATUS_REG.

    attrs field of attribute_group structure is a pointer to a pointer (as in
    an array of pointers) rather than pointer to attribute struct (as in an
    array of structures), so when allocating size of the pointer sholud be
    used instead of the structure it is pointing to.

    While at it, also change the call to use kcalloc rather than kzalloc.

  • 0ab30494b   memstick: add support for legacy memorysticks ... Browse Code »

    Based partially on MS standard spec quotes from Alex Dubov.

    As any code that works with user data this driver isn't recommended to use
    to write cards that contain valuable data.

    It tries its best though to avoid data corruption and possible damage to
    the card.

    Tested on MS DUO 64 MB card on Ricoh R592 card reader.

    The driver core clears the driver data to NULL after device_release or on
    probe failure. Thus, it is not needed to manually clear the device driver
    data to NULL.

    Pull MFS updates from Samuel Ortiz:
    "This is the MFD pull request for the 3.9 merge window.

    No new drivers this time, but a bunch of fairly big cleanups:

    - Roger Quadros worked on a OMAP USBHS and TLL platform data
    consolidation, OMAP5 support and clock management code cleanup.

    - The first step of a major sync for the ab8500 driver from Lee
    Jones. In particular, the debugfs and the sysct interfaces got
    extended and improved.

    - Peter Ujfalusi sent a nice patchset for cleaning and fixing the
    twl-core driver, with a much needed module id lookup code
    improvement.

    - The regular wm5102 and arizona cleanups and fixes from Mark Brown.

    - Laxman Dewangan extended the palmas APIs in order to implement the
    palmas GPIO and rt drivers.

    - Laxman also added DT support for the tps65090 driver.

    - The Intel SCH and ICH drivers got a couple fixes from Aaron Sierra
    and Darren Hart.

    - Linus Walleij patchset for the ab8500 driver allowed ab8500 and
    ab9540 based devices to switch to the new abx500 pin-ctrl driver.

    - The max8925 now has device tree and irqdomain support thanks to
    Qing Xu.

    - The recently added rtsx driver got a few cleanups and fixes for a
    better card detection code path and now also supports the RTS5227
    chipset, thanks to Wei Wang and Roger Tseng."

  • c3481955f   mfd: rtsx: Fix issue that booting OS with SD card inserted ... Browse Code »

    Realtek card reader supports both SD and MS card. According to the
    settings of rtsx MFD driver, SD host will be probed before MS host.
    If we boot/reboot Linux with SD card inserted, the resetting flow of SD
    card will succeed, and the following resetting flow of MS is sure to fail.
    Then MS upper-level driver will ask rtsx driver to turn power off. This
    request leads to the result that the following SD commands fail and SD card
    can't be accessed again.

    In this commit, Realtek's SD and MS host driver will check whether the card
    that upper driver requesting is the one existing in the slot. If not, Realtek's
    host driver will refuse the operation to make sure the exlusive accessing
    at the same time.

  • 41d9c644f   memstick: change to new flag variable ... Browse Code »

    The EXTRA_CFLAGS assignment in memstick/Makefile was not accomplishing
    anything because this flag only has effect on sources at the same level
    as the makefile (i.e., per directory). Since both core/ and host/ rely
    on MEMSTICK_DEBUG, the subdir-ccflags-y variant seems to be the
    appropriate choice.

    There are two spellings in use for 'freeze' + 'able' - 'freezable' and

    mostly used by workqueue and in a few other odd places. Unify the

  • 2a48fc0ab   block: autoconvert trivial BKL users to private mutex ... Browse Code »

    The block device drivers have all gained new lock_kernel
    calls from a recent pushdown, and some of the drivers
    were already using the BKL before.

    This turns the BKL into a set of per-driver mutexes.
    Still need to check whether this is safe to do.

    file=$1
    name=$2
    if grep -q lock_kernel ${file} ; then
    if grep -q 'include.*linux.mutex.h' ${file} ; then

  • 6e9624b8c   block: push down BKL into .open and .release ... Browse Code »

    The open and release block_device_operations are currently
    called with the BKL held. In order to change that, we must
    first make sure that all drivers that currently rely
    on this have no regressions.

    This blindly pushes the BKL into all .open and .release
    operations for all block drivers to prepare for the
    next step. The drivers can subsequently replace the BKL
    with their own locks or remove it completely when it can
    be shown that it is not needed.

    The functions blkdev_get and blkdev_put are the only
    remaining users of the big kernel lock in the block
    layer, besides a few uses in the ioctl code, none
    of which need to serialize with blkdev_{get,put}.

    Most of these two functions is also under the protection
    of bdev->bd_mutex, including the actual calls to
    ->open and ->release, and the common code does not
    access any global data structures that need the BKL.
