Subject: ar71xx: spi-rb4xx: balance clk_prepare_enable() call
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6456999731fa8d22419ffeef9c1710e484620c80;p=openwrt%2Fstaging%2Fthess.git

ar71xx: spi-rb4xx: balance clk_prepare_enable() call

Commit c312cef223dd ("ar71xx: spi-rb4xx fix.") replaced the clk_enable() call
with clk_prepare_enable() to meet the common clock framework requirements.
However it did not change the clk_disable() call in the error patch which
thus leads to imbalance.

Fix the code by using the correct counterpart of clk_prepare_enable() in both
places.
