X-Git-Tag: firefly_0821_release~3680^2~4273^2~183^2~38^2~9
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=d3b104ae22a761dbec8410e6e66ac048c9ff9b5f;p=firefly-linux-kernel-4.4.55.git

wl12xx: fix sdio_test module functionality

Due to some changes in PM in recent kernels, the sdio_test module has
been broken for a while.  This patch fixes the code that powers the
card on and off.

Also made some small indentation fixes in the Makefile.

[Rephrased commit log and removed the change in the FW name, since
it's done in another patch. -- Luca]
