In case of error, the function of_iomap() returns NULL pointer not
ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.

Fixes: a2e230c7b2ea ("clk: Add clock driver for ASPEED BMC SoCs")

Same comment for this. I suspect coccinelle is finding this but
the semantic patch is not in the kernel repo?
