Revision 3d3801effda19b21012b5d1981e96cc277df85fd authored by Michael Turquette on 25 February 2015, 17:11:01 UTC, committed by Stephen Boyd on 11 March 2015, 22:56:59 UTC
Some drivers compare struct clk pointers as a means of knowing
if the two pointers reference the same clock hardware. This behavior is
dubious (drivers must not dereference struct clk), but did not cause any
regressions until the per-user struct clk patch was merged. Now the test
for matching clk's will always fail with per-user struct clk's.
clk_is_match is introduced to fix the regression and prevent drivers
from comparing the pointers manually.
