Subject: x86: Replace the EVT_TO_HPET_DEV() macro with an inline function
X-Git-Tag: v3.3-rc1~187^2~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3f7787b36cf2d99f3dbc8a0be85b92a5530a9a76;p=profile%2Fivi%2Fkernel-x86-ivi.git

x86: Replace the EVT_TO_HPET_DEV() macro with an inline function

The original macro worked only when applied to variables named
'evt'. While this could have been fixed by simply renaming the
macro argument, a more type-safe replacement is preferred.
