gcc thinks that interpreting a multiplication result as a bool is confusing: drivers/gpu/drm/nouveau/nvkm/subdev/clk/gt215.c: In function 'read_pll': drivers/gpu/drm/nouveau/nvkm/subdev/clk/gt215.c:133:8: error: '*' in boolean context, suggest '&&' instead [-Werror=int-in-bool-context] In this instance, I think using multiplication is more intuitive than '&&', so I'm adding a comparison to zero instead to shut up the warning. To further improve readability, I also make the error case indented and leave the normal case as the final 'return' statement.
