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

2020-01-23T07:21:39Z

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: Don't reference clk_init_data after registration

2019-10-07T16:56:45Z

[ 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.
