Subject: hrtimer: Annotate hrtimer_cpu_base_.*_expiry() for sparse.
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=330dd6d9c0fce69718b53ca0bc4f2e3920f7f600;p=linux.git

hrtimer: Annotate hrtimer_cpu_base_.*_expiry() for sparse.

The two hrtimer_cpu_base_.*_expiry() functions are wrappers around the
locking functions and sparse complains about the missing counterpart.

Add sparse annotation to denote that this bevaviour is expected.
