Subject: crypto: inside-secure - fix clock management
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f962eb46e7a9b98a58d2483f5eb216e738fec732;p=openwrt%2Fstaging%2Fblogic.git

crypto: inside-secure - fix clock management

In this driver the clock is got but never put when the driver is removed
or if there is an error in the probe.

Using the managed version of clk_get() allows to let the kernel take care
of it.

Fixes: 1b44c5a60c13 ("crypto: inside-secure - add SafeXcel EIP197 crypto
engine driver")
