[PATCH] staging:fbtft:Fix build warnings for incorrently using %d for size_t variables in dev_err statements

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

 



Fixes the build warnings for using %d for a variable of type size_t in dev_err statements
for the functions,fbtft_read_spi and fbtft_write_spi_emulate_9 respectfully by changing
both dev_error calls to use the correct format specifier for size_t instead.
