  • f423fc627   Revert "rtc: Expire alarms after the time is set." ... Browse Code »

    This reverts commit 93b2ec0128c431148b216b8f7337c1a52131ef03.

    The call to "schedule_work()" in rtc_initialize_alarm() happens too
    early, and can cause oopses at bootup

    Neil Brown explains why we do it:

    "If you set an alarm in the future, then shutdown and boot again after
    that time, then you will end up with a timer_queue node which is in
    the past.

    When this happens the queue gets stuck. That entry-in-the-past won't
    get removed until and interrupt happens and an interrupt won't happen
    because the RTC only triggers an interrupt when the alarm is "now".

    So you'll find that e.g. "hwclock" will always tell you that
    'select' timed out.

    So we force the interrupt work to happen at the start just in case."

    and has a patch that convert it to do things in-process rather than with
    the worker thread, but right now it's too late to play around with this,
    so we just revert the patch that caused problems for now.

    1

    This reverts commit c0afabd3d553c521e003779c127143ffde55a16f.

    It causes failures on Toshiba laptops - instead of disabling the alarm,
    it actually seems to enable it on the affected laptops, resulting in
    (for example) the laptop powering on automatically five minutes after
    shutdown.

    There's a patch for it that appears to work for at least some people,
    but it's too late to play around with this, so revert for now and try
    again in the next merge window.

    See for example

  • b015dbc0f   mwifiex: fix crash during simultaneous scan and connect ... Browse Code »

    If 'iw connect' command is fired when driver is already busy in
    serving 'iw scan' command, ssid specific scan operation for connect
    is skipped. In this case cmd wait queue handler gets called with no
    command in queue (i.e. adapter->cmd_queued = NULL).

    This patch adds a NULL check in mwifiex_wait_queue_complete()
    routine to fix crash observed during simultaneous scan and assoc
    operations.

    don't do aggregation related stuff for 'AP mode client power save
    handling' if aggregation is not enabled in the driver, otherwise it
    will lead to panic because those data structures won't be never
    intialized in 'ath_tx_node_init' if aggregation is disabled

  • 0d9032477   net: fsl: fec: fix build for mx23-only kernel ... Browse Code »

    If one only selects mx23-based boards, compile fails:

    drivers/net/ethernet/freescale/fec.c:410:2: error: 'FEC_HASH_TABLE_HIGH' undeclared (first use in this function)
    drivers/net/ethernet/freescale/fec.c:411:2: error: 'FEC_HASH_TABLE_LOW' undeclared (first use in this function)

    This is because fec.h uses CONFIG_SOC_IMX28 to determine the register
    layout of the core which makes sense since the MX23 does not have a fec.
    However, Kconfig uses the broader ARCH_MXS symbol and this way even
    makes the fec-driver default for MX23. Adapt Kconfig to use the more
    precise SOC_IMX28 as well.

  • ac97ecc88   gspca: Fix falling back to lower isoc alt settings ... Browse Code »

    The current gspca core code has a regression where it no longer properly
    falls back to lower alt settings when there is not enough bandwidth.

    This causes many iso based usb-1 cameras to not work when plugged into a
    usb2 hub or a sandybridge chipset motherboard!

    This patch fixes this.
