Subject: mmc: card: mmc_test: Simplify a trivial if-return sequence
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=30a9b9e1efe63e883063afc0f44a6f204b90c334;p=linux-beck.git

mmc: card: mmc_test: Simplify a trivial if-return sequence

Simplify a trivial if-return sequence. Possibly combine with a
preceding function call.

The semantic patch that makes this change is available
in scripts/coccinelle/misc/simple_return.cocci.

More information about semantic patching is available at
