clk: sprd: return correct type of value for _sprd_pll_recalc_rate

2020-06-25T13:33:00+00:00

[ Upstream commit c2f30986d418f26abefc2eec90ebf06716c970d2 ] The function _sprd_pll_recalc_rate() defines return value to unsigned long, but it would return a negative value when malloc fail, changing to return its parent_rate makes more sense, since if the callback .recalc_rate() is not set, the framework returns the parent_rate as well.

clk: sprd: Use IS_ERR() to validate the return value of syscon_regmap_lookup_by_phandle()

2020-01-23T07:21:39+00:00

commit 9629dbdabd1983ef53f125336e1d62d77b1620f9 upstream. The syscon_regmap_lookup_by_phandle() will never return NULL, thus use IS_ERR() to validate the return value instead of IS_ERR_OR_NULL().

clk: sprd: add missing kfree

[ 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

2019-10-07T16:56:45+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.
