The patch titled Subject: drivers/rtc/rtc-ab8500.c: change msleep() to usleep_range() has been removed from the -mm tree. Its filename was rtc-ab8500-change-to-msleep-to-usleep_range.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ From: Linus Walleij <linus.walleij@xxxxxxxxxx> Subject: drivers/rtc/rtc-ab8500.c: change msleep() to usleep_range() The resolution of msleep is related to HZ, so with HZ set to 100 any msleep of less than 10ms will become ~10ms. This is not what we want. Use the hrtimer-based usleep_range() and allow for some slack in the non-critical path so we have more control of what is happening here.
