Subject: [PATCH] gpio: amd-fch: correct logic of GPIO_LINE_DIRECTION
Git-commit: d25e8fdebdad84219b498873300b7f11dd915b88
Patch-mainline: v5.9-rc8
References: git-fixes
The original commit appears to have the logic reversed in
amd_fch_gpio_get_direction. Also confirmed by observing the value of
"direction" in the sys tree.
