From: Linus Walleij Date: Tue, 28 Mar 2017 08:40:29 +0000 (+0200) Subject: mmc: core: move some code in mmc_start_areq() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5744d50d2d9e7efdae4b5d13cd71f49256ada6ba;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git mmc: core: move some code in mmc_start_areq() "previous" is a better name for the variable storing the previous asynchronous request, better than the opaque name "data" atleast. We see that we assign the return status to the returned variable on all code paths, so we might as well just do that immediately after calling mmc_finalize_areq().
