[PATCH 0/4] ALSA: Fix compiler warnings in sound subsystem
Posted by wangdich9700@163.com 1 week ago
From: wangdicheng <wangdicheng@kylinos.cn>

This series fixes four compiler warnings in the sound subsystem,
covering both logical redundancies and potential runtime bugs.

Two categories of warnings are addressed:

1. "possible condition with no effect (if == else)" -- redundant
   conditional branches that produce identical code. These are
   cosmetic issues but should be cleaned up.

2. "do_div() does a 64-by-32 division" -- use of do_div() with
   a 64-bit divisor, which silently truncates the upper 32 bits.
   These are potential runtime bugs on 64-bit platforms where the
   divisor may exceed the 32-bit range.

Patches 1-2 fix the if==else warnings.
Patches 3-4 fix the do_div() warnings.

wangdicheng (4):
  ASoC: mediatek: mt8189: Remove redundant else-if branch with identical
    body
  ALSA: sparc/dbri: Fix "possible condition with no effect" warning
  ASoC: fsl_easrc: Use div64_u64 for 64-by-64 division
  ASoC: tlv320aic32x4: Use div64_ul for division by unsigned long
