pinctrl: imx-iomux-v3: fix compiler warning
Fix a warning while compiling with GCC 5.4.0 (OSELAS.Toolchain 2016.02):
drivers/pinctrl/imx-iomux-v3.c: In function 'imx_iomux_v3_set_state':
drivers/pinctrl/imx-iomux-v3.c:153:13: warning: 'share_conf_val' may be used uninitialized in this function [-Wmaybe-uninitialized]
conf_val &= ~IMX_PAD_SION;
we have the pattern:
if (share_conf)
share_conf_val = ...;
...
if (share_conf)
use(share_conf_val);
GCC 5.4.0 doesn't recognize this so explicitly initialize
share_conf_val.
