Signed-off-by: Vladimir Barinov [Sergei: added 'id' parameter check to r8a7779_add_vin_device(), used '*pdata' in *sizeof* operator there, renamed some variables, annotated vin[0-3]_resources [] and 'vin[0-3]_info' as '__initdata'.] Signed-off-by: Sergei Shtylyov --- Changes since version 3: - changed the VIN platform device name to be R8A7779 specific; - used '*pdata' in *sizeof* operator in r8a7779_add_vin_device(); - resolved reject in due to USB patch rework. Changes since version 2: - annotated vin[0-3]_resources[] and 'vin[0-3]_info' as '__initdata' since they are kmemdup()'ed while registering the platform devices anyway; Changes since the original posting: - added 'id' parameter check to r8a7779_add_vin_device(). arch/arm/mach-shmobile/clock-r8a7779.c | 10 +++++++ arch/arm/mach-shmobile/include/mach/r8a7779.h | 3 ++ arch/arm/mach-shmobile/setup-r8a7779.c | 37 ++++++++++++++++++++++++++ 3 files changed, 50 insertions(+) -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Index: renesas/arch/arm/mach-shmobile/clock-r8a7779.c =================================================================== --- renesas.orig/arch/arm/mach-shmobile/clock-r8a7779.c +++ renesas/arch/arm/mach-shmobile/clock-r8a7779.c @@ -112,7 +112,9 @@ static struct clk *main_clks[] = { };
