Subject: [PATCH 047/114] spi-bcm2708: Prepare for Common Clock Framework
|
|
migration
|
|
|
|
As part of migrating to use the Common Clock Framework, replace clk_enable()
|
|
with clk_prepare_enable() and clk_disable() with clk_disable_unprepare().
|
|
This does not affect behaviour under the current clock implementation.
|
|
|
|
Also add a missing clk_disable_unprepare() in the probe error path.
|
|
