      ASoC: wm8962: Turn on regcache_cache_only before disabling regulator · 50bfcf2d
      Nicolin Chen authored
      It's safer to turn on regcache_cache_only before disabling regulator since
      the driver will turn off the regcache_cache_only after enabling regulator.
      
      If we remain cache_only false, some command like 'amixer cset' would get
      failure if being run before wm8962_resume().

      ASoC: fsl: imx-pcm-fiq: omit fiq counter to avoid harm in unbalanced situations · fc7dc61d
      Oskar Schirmer authored
      Unbalanced calls to snd_imx_pcm_trigger() may result in endless
      FIQ activity and thus provoke eternal sound. While on the first glance,
      the switch statement looks pretty symmetric, the SUSPEND/RESUME
      pair is not: the suspend case comes along snd_pcm_suspend_all(),
      which for fsl/imx-pcm-fiq is called only at snd_soc_suspend(),
      but the resume case originates straight from the SNDRV_PCM_IOCTL_RESUME.
      This way userland may provoke an unbalanced resume, which might cause
      the fiq_enable counter to increase and never return to zero again,
      so eventually imx_pcm_fiq is never disabled.
      
      Simply removing the fiq_enable will solve the problem, as long as
      one never goes play and capture game simultaneously, but beware
      trying both at once, the early TRIGGER_STOP will cut off the other
      activity prematurely. So now playing and capturing is scrutinized
      separately, instead of by counting.

      scripts/kallsyms: filter symbols not in kernel address space · f6537f2f
      Ming Lei authored
      This patch uses CONFIG_PAGE_OFFSET to filter symbols which
      are not in kernel address space because these symbols are
      generally for generating code purpose and can't be run at
      kernel mode, so we needn't keep them in /proc/kallsyms.
      
      For example, on ARM there are some symbols which may be
      linked in relocatable code section, then perf can't parse
      symbols any more from /proc/kallsyms, this patch fixes the
      problem (introduced b9b32bf7)

       "Here is a set of patches that revert all of the changes done to the
        pl2303 USB serial driver in the 3.12-rc timeframe, as it turns out
        they break some devices that work just fine on 3.11.  As it's not a
        good idea to break working systems, drop them all and they will be
        reworked for future kernel versions such that there is no breakage.
      
        I've also included a MAINTAINERS update for the USB serial subsystem
        and a new device id for the ftdi_sio driver as well"
