[PATCH] Input: matrix_keypad - depend on CONFIG_PM_SLEEP for suspend/resume functions

[PATCH] Input: matrix_keypad - depend on CONFIG_PM_SLEEP for suspend/resume functions

[Tobias Doerffel]

When building a kernel with CONFIG_PM=y but neither suspend nor
hibernate support, the compiler complains about the static functions
matrix_keypad_suspend() and matrix_keypad_resume() not being used:

drivers/input/keyboard/matrix_keypad.c:219:12: warning: ‘matrix_keypad_suspend’ defined but not used
drivers/input/keyboard/matrix_keypad.c:242:12: warning: ‘matrix_keypad_resume’ defined but not used

Depending on CONFIG_PM_SLEEP rather than CONFIG_PM fixes the issue.
