From: Vipin K Parashar Date: Mon, 31 Aug 2015 23:22:43 +0000 (+0530) Subject: powerpc/opal: Assign numbers to OPAL_MSG macros of enum opal_msg_type X-Git-Tag: v4.7-rc1~108^2~172 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=b3d79eaa6c97b04965fa479652dd0317253f81d1;p=linux.git powerpc/opal: Assign numbers to OPAL_MSG macros of enum opal_msg_type This patch assigns numbers to OPAL_MSG macros of enum opal_msg_type to prevent accidental insertion of any new value in between and thus break OPAL API. This is also helpful while backporting mainline kernel changes to distros which run downlevel kernel and thus don't have all OPAL messages defined, avoiding unnecessary bugs due to enum values order mismatch.
