Subject: spi: mpc8xxx: Fix comments
X-Git-Tag: v2019.07-rc4~1^2~17
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d93fe31020d138ca5f4fc1c8afce5acb8f724823;p=platform%2Fkernel%2Fu-boot.git

spi: mpc8xxx: Fix comments

There are some comments on the same line as the code they document. Put
comments above the code lines they document, so the line length is not
unnecessarily increased.
