  • 9063f1f15   mfd: Fix NULL pointer due to non-initialized ucb1x00-ts absinfo ... Browse Code »

    Call input_set_abs_params instead of manually setting absbit only.
    This fixes this oops:

  • dcea83adc   [ARM] Hide ISA DMA API when ISA_DMA_API is unset ... Browse Code »

    When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
    so there's no point in publishing the prototypes via asm/dma.h, nor
    including the machine dependent parts of that API.

    This allows us to remove a lot of mach/dma.h files which don't contain
    any useful code. Unfortunately though, some platforms put their own
    private non-ISA definitions into mach/dma.h, so we leave these behind
    and fix the appropriate #include statments.

  • f7440b0ec   mfd: use shorter set_current_state() ... Browse Code »

    Since this routine declares a separate "tsk" pointer for no other reason than
    to call set_task_state(), get rid of it and just invoke set_current_state().

  • 831441862   Freezer: make kernel threads nonfreezable by default ... Browse Code »

    Currently, the freezer treats all tasks as freezable, except for the kernel
    threads that explicitly set the PF_NOFREEZE flag for themselves. This
    approach is problematic, since it requires every kernel thread to either
    set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
    care for the freezing of tasks at all.

    It seems better to only require the kernel threads that want to or need to
    be frozen to use some freezer-related code and to remove any
    freezer-related code from the other (nonfreezable) kernel threads, which is
    done in this patch.

    The patch causes all kernel threads to be nonfreezable by default (ie. to
    have PF_NOFREEZE set by default) and introduces the set_freezable()
    function that should be called by the freezable kernel threads in order to
    unset PF_NOFREEZE. It also makes all of the currently freezable kernel
    threads call set_freezable(), so it shouldn't cause any (intentional)
    change of behaviour to appear. Additionally, it updates documentation to
    describe the freezing of tasks more accurately.

  • 1393c3edc   [PATCH] input: fix ucb1x00-ts breakage after conversion to dynamic input_dev allocation ... Browse Code »

    The bd622663192e8ebebb27dc1d9397f352a82d2495 commit broke the UCB1x00
    touchscreen driver since the idev structure was assumed to be into the ts
    structure, simply casting the former to the later in a couple places.

    This patch fixes those, and also cache the idev pointer between multiple
    calls to input_report_abs() to avoid growing the compiled code needlessly.
