clk: sprd: add missing kfree

2019-10-07T16:59:22+00:00

[ Upstream commit 5e75ea9c67433a065b0e8595ad3c91c7c0ca0d2d ]

The number of config registers for different pll clocks probably are not
same, so we have to use malloc, and should free the memory before return.

clk: sprd: Don't reference clk_init_data after registration

2019-10-07T16:59:08+00:00

[ Upstream commit f6c90df8e7e33c3dc33d4d7471bc42c232b0510e ]

A future patch is going to change semantics of clk_register() so that
clk_hw::init is guaranteed to be NULL after a clk is registered. Avoid
referencing this member here so that we don't run into NULL pointer
exceptions.

clk: sprd: Add check for return value of sprd_clk_regmap_init()

2019-08-06T17:08:06+00:00

[ Upstream commit c974c48deeb969c5e4250e4f06af91edd84b1f10 ]

sprd_clk_regmap_init() doesn't always return success, adding check
for its return value should make the code more strong.
