[PATCH v3 1/2] PCI: histb: Fix error path of histb_pcie_host_enable()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If clk_prepare_enable() call fails on a particular clock, we should not
call clk_disable_unprepare() on this clock, but on the clocks that
succeed from clk_prepare_enable() previously.
