For Exynos' pinmux UART implementation there was a possibility to run for() statement with uninitialized bank, start and count values. Those warnings appear when following toolchain is used (gcc-4.8.2-glibc-2.18-binutils-2.24): warning: 'count' may be used uninitialized in this function [-Wmaybe-uninitialized] Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Cc: Minkyu Kang <mk7.kang@samsung.com> --- arch/arm/cpu/armv7/exynos/pinmux.c | 9 +++++++++ 1 file changed, 9 insertions(+)
