commit 51bddd4501bc414b8b1e8f4d096b4a5304068169 upstream.
The purpose of commit 0fd85869c2a9 ("spi/bcm63xx-hsspi: keep pll clk enabled") was to keep the pll clk enabled through the lifetime of the device.
In order to do that, some 'clk_prepare_enable()'/'clk_disable_unprepare()' calls have been added in the error handling path of the probe function, in the remove function and in the suspend and resume functions.
However, a 'clk_disable_unprepare()' call has been unfortunately left in the probe function. So the commit seems to be more or less a no-op.
Axe it now, so that the pll clk is left enabled through the lifetime of the device, as described in the commit.
