[PATCH] RTC: Return -EBUSY, not -EACCES when device is busy

From: Chris Brand If rtc->irq_task is non-NULL and task is NULL, they always differ, which means that in rtc_irq_set_state() and rtc_irq_set_freq(), whenever err is set to -EBUSY it will then immediately be set to -EACCES, misleading the caller as to the underlying problem. --- drivers/rtc/inter

Re-send of patch to broader audience

I originally sent this patch 4 Apr [1] and 17 Apr [2] to the rtc mailing list and maintainer, but saw no responses. I think it's pretty clear that the original code is wrong. Hopefully third time's the charm... Chris [1] https://groups.google.com/forum/?fromgroups=#!topic/rtc-linux/GrsRzUH1ORc [
