spi: Fix comparison of different integer types
Fix problem discovered with sparse: + drivers/spi/spi.c:1554:37: sparse: incompatible types in comparison expression (different signedness) drivers/spi/spi.c: In function 'spi_write_then_read': drivers/spi/spi.c:1554:23: warning: comparison of distinct pointer types lacks a cast [enabled by default] The change to SPI_BUFSIZ was introduced in commit b3a223ee2, "spi: Remove SPI_BUFSIZ restriction on spi_write_then_read()" Cc: Mark Brown <broonie@opensource.wolfsonmicro.com> Reported-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
