Input: omap4-keypad - fix pm_runtime_get_sync() error checking
[ Upstream commit 81022a170462d38ea10612cb67e8e2c529d58abe ]
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")
