Adding an explicit initialization to -EINVAL here is correct even if the caller changed, and it avoids the warning on gcc-4.9 as well.

The rework of the exynos DRM clock handling introduced warnings for configurations that have CONFIG_PM disabled: drivers/gpu/drm/exynos/exynos_hdmi.c:736:13: error: 'hdmi_clk_disable_gates' defined but not used [-Werror=unused-function] static void hdmi_clk_disable_gates(struct hdmi_context *hdata) ^~~~~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/exynos/exynos_hdmi.c:717:12: error: 'hdmi_clk_enable_gates' defined but not used [-Werror=unused-function] static int hdmi_clk_enable_gates(struct hdmi_context *hdata) The problem is that the PM functions themselves are inside of an #ifdef, but some functions they call are not. This patch removes the #ifdef and instead marks the PM functions as __maybe_unused, which is a more reliable way to get it right.

On x86, the cw1200 driver produces a rather silly warning about the possible use of the 'ret' variable without an initialization presumably after being confused by the architecture specific definition of WARN_ON: drivers/net/wireless/st/cw1200/wsm.c: In function ‘wsm_handle_rx’: drivers/net/wireless/st/cw1200/wsm.c:1457:9: error: ‘ret’ may be used uninitialized in this function [-Werror=maybe-uninitialized] We have already checked that 'count' is larger than 0 here, so we know that 'ret' is initialized. Changing the 'for' loop into do/while also makes this clear to the compiler.
