[PATCH] drivers: net: phy: xgene: Fix 'remove' function

From: Christophe JAILLET
Date: Sun Sep 11 2016 - 15:44:03 EST


If 'IS_ERR(pdata->clk)' is true, then 'clk_disable_unprepare(pdata->clk)'
will do nothing.

It is likely that 'if (!IS_ERR(pdata->clk))' was expected here.
In fact, the test can even be removed because 'clk_disable_unprepare'
already handles such cases.
