dmaengine: cirrus: use snprintf() to calm down gcc 13.3.0
Even though it's a false positive (highest channel number is "9"), refer to "struct ep93xx_edma_data edma_m2p", we can avoid new warning by using snprintf(). drivers/dma/ep93xx_dma.c: In function 'ep93xx_dma_of_probe': >> drivers/dma/ep93xx_dma.c:1365:51: warning: '%u' directive writing between 1 and 8 bytes into a region of size 2 [-Wformat-overflow=] 1365 | sprintf(dma_clk_name, "m2p%u", i); | ^~ drivers/dma/ep93xx_dma.c:1365:47: note: directive argument in the range [0, 16777216] 1365 | sprintf(dma_clk_name, "m2p%u", i); | ^~~~~~~ drivers/dma/ep93xx_dma.c:1365:25: note: 'sprintf' output between 5 and 12 bytes into a destination of size 5 1365 | sprintf(dma_clk_name, "m2p%u", i); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Fixes: 4e8ad5ed845b ("dmaengine: cirrus: Convert to DT for Cirrus EP93xx") Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202409122133.NctarRoK-lkp@intel.com/ Signed-off-by: Alexander Sverdlin <alexander.sverdlin@gmail.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
