[ Upstream commit 7256d1f4618b40792d1e9b9b6cb1406a13cad2dd ]
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().
