From: Charulatha V <redacted> Modify omap_gpio_prepare_for_idle() & omap_gpio_resume_after_idle() functions to handle save context & restore context respectively in the OMAP GPIO driver itself instead of calling these functions from pm specific files. For this, in gpio_prepare_for_idle(), call *_get_context_loss_count() and in gpio_resume_after_idle() call it again. If the count is different, do restore context. The workaround_enabled flag is no more required and is removed. Signed-off-by: Charulatha V <redacted> Signed-off-by: Tarun Kanti DebBarma <redacted> Reviewed-by: Santosh Shilimkar <redacted>

no #ifdef please (c.f. "#ifdefs are ugly" in Documentation/SubmittingPatches) In this case, the existence of this API isn't dependent on CONFIG_PM, so the #ifdef isn't right. Kevin
