Subject: sh-pfc: Terminate gpios array by -1
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=316b2550015dc8d26fb1395826533e9ef3434da9;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git
sh-pfc: Terminate gpios array by -1
0 is a valid GPIO value, use -1 to terminate the gpios array in IRQ
lists.
