Subject: clk: Merge prepare and unprepare sections
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d94f0f096ccf83b1a212788c62122c4b97ac8907;p=thirdparty%2Flinux.git

clk: Merge prepare and unprepare sections

<linux/clk.h> contains two consecutive #ifdef/#else/#endif sections
that check for CONFIG_HAVE_CLK_PREPARE: one for prepare-related
functionality, and a second for unprepare-related functionality.
Reduce #ifdef clutter by merging them.
