Subject: [PATCH] Input: omap4-keypad - fix pm_runtime_get_sync() error checking
Git-commit: 81022a170462d38ea10612cb67e8e2c529d58abe
Patch-mainline: v5.18-rc4
References: git-fixes
If the device is already in a runtime PM enabled state
pm_runtime_get_sync() will return 1, so a test for negative
value should be used to check for errors.
Fixes: f77621cc640a ("Input: omap-keypad - dynamically handle register offsets")
