From: Gavin Shan Date: Thu, 8 Oct 2015 03:58:58 +0000 (+1100) Subject: powerpc/powernv: Remove pnv_eeh_cap_start() X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4d6186ca6f55b2f71be643af8a112c25e58ac516;p=linux-beck.git powerpc/powernv: Remove pnv_eeh_cap_start() This moves the logic of pnv_eeh_cap_start() to pnv_eeh_find_cap() as the function is only called by pnv_eeh_find_cap(). The logic of both functions are pretty simple. No need to have separate functions.
