[-- Attachment #1: hrtimer_Cleanup_clock_argument_in_schedule_hrtimeout_range_clock.patch --]
[-- Type: text/plain, Size: 2902 bytes --]

From: Anna-Maria Gleixner <anna-maria@linutronix.de>

schedule_hrtimeout_range_clock() uses an integer for the clock id
instead of the predefined type "clockid_t". The ID of the clock is
indicated in hrtimer code as clock_id. Therefore change the name of
the variable as well to make it consistent.

While at it, clean up the description for the function parameters clock_id
and mode. The clock modes and the clock ids are not restricted as the
comment suggests. Fix the mode description as well for the callers of
schedule_hrtimeout_range_clock().

No functional change.
