[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Fix sparse warnings:

drivers/staging/wfx/fwio.c:83:5: warning: symbol 'sram_write_dma_safe' was not declared. Should it be static?
drivers/staging/wfx/fwio.c:229:5: warning: symbol 'load_firmware_secure' was not declared. Should it be static?
