Fix ATMEL_LCDC_MEMOR and ATMEL_LCDC_MEMOR_LITTLE defines to use "U" cast to avoid shifting signed 32 bit values by 31 bit problem. This problem. This is not a problem for gcc built kernel.
However, this may be a problem since the header is part of pbulic API which could be included for builds using compilers which do not handle this condition safely resulting in undefined behavior Signed-off-by: Shobhit Kukreti <[email protected]> --- include/video/atmel_lcdc.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/include/video/atmel_lcdc.h b/include/video/atmel_lcdc.h index 43e497c..ac96b4f 100644 --- a/include/video/atmel_lcdc.h +++ b/include/video/atmel_lcdc.h @@ -103,9 +103,9 @@ struct atmel_lcdfb_pdata { #define ATMEL_LCDC_CLKMOD (1 << 15) #define ATMEL_LCDC_CLKMOD_ACTIVEDISPLAY (0 << 15) #define ATMEL_LCDC_CLKMOD_ALWAYSACTIVE (1 << 15) -#define ATMEL_LCDC_MEMOR (1 << 31) +#define ATMEL_LCDC_MEMOR (1U << 31) #define ATMEL_LCDC_MEMOR_BIG (0 << 31) -#define ATMEL_LCDC_MEMOR_LITTLE (1 << 31) +#define ATMEL_LCDC_MEMOR_LITTLE (1U << 31) #define ATMEL_LCDC_TIM1 0x0808 #define ATMEL_LCDC_VFP (0xffU << 0) -- 2.7.4
