Subject: [PATCH 5.2 005/144] iio: adc: gyroadc: fix uninitialized return code
From: Arnd Bergmann <arnd@...db.de>
commit 90c6260c1905a68fb596844087f2223bd4657fee upstream.
gcc-9 complains about a blatant uninitialized variable use that
all earlier compiler versions missed:
drivers/iio/adc/rcar-gyroadc.c:510:5: warning: 'ret' may be used uninitialized in this function [-Wmaybe-uninitialized]
Return -EINVAL instead here and a few lines above it where
we accidentally return 0 on failure.
Cc: stable@...r.kernel.org
