Before commit 5c29e47e6ac55b63c76999eb5b283a80208726c5 ("mfd: cros_ec_spi: Warnings fix"), 64-bit compiles gave the following warnings:
drivers/mfd/cros_ec_spi.c: In function 'cros_ec_spi_receive_response': drivers/mfd/cros_ec_spi.c:123:5: warning: format '%d' expects argument of type 'int', but argument 4 has type 'long int' [-Wformat] drivers/mfd/cros_ec_spi.c:157:3: warning: format '%d' expects argument of type 'int', but argument 6 has type 'long int' [-Wformat] drivers/mfd/cros_ec_spi.c:181:2: warning: format '%d' expects argument of type 'int', but argument 4 has type 'long int' [-Wformat]
After that commit, 32-bit compiles give:
drivers/mfd/cros_ec_spi.c: In function ‘cros_ec_spi_receive_response’: drivers/mfd/cros_ec_spi.c:123: warning: format ‘%ld’ expects type ‘long int’, but argument 4 has type ‘int’ drivers/mfd/cros_ec_spi.c:157: warning: format ‘%ld’ expects type ‘long int’, but argument 6 has type ‘int’ drivers/mfd/cros_ec_spi.c:181: warning: format ‘%ld’ expects type ‘long int’, but argument 4 has type ‘int’
Use %z to format pointer differences to kill the warnings on both 32-bit and 64-bit.
