Subject: [PATCH 1/1] clk: mxl: Fix smatch static checker warning
Commit 036177310bac: ("clk: mxl: Switch from direct readl/writel based IO to
regmap based IO") introduced code resulting in below warning issued by the
smatch static checker.
drivers/clk/x86/clk-lgm.c:441 lgm_cgu_probe()
warn: passing zero to 'PTR_ERR'
Fix the warning by replacing incorrect IS_ERR_OR_NULL() with IS_ERR().

regmap based IO")
