Subject: [PATCH 3/3] ASoC: meson: axg-spdifin: remove comparison always false warning
Date: Tue, 7 Jul 2020 14:23:10 -0500 [thread overview]
Message-ID: <20200707192310.98663-4-pierre-louis.bossart@linux.intel.com> (raw)
In-Reply-To: <20200707192310.98663-1-pierre-louis.bossart@linux.intel.com>
Fix W=1 warning:
sound/soc/meson/axg-spdifin.c: In function ‘axg_spdifin_write_mode_param’:
include/linux/bits.h:26:28: warning: comparison of unsigned expression
< 0 is always false [-Wtype-limits]
Cast width to an int to avoid checking if an unsigned value is lower
than zero.
