From: Rajeshwar R Shinde <coolrrsh@gmail.com> In struct mpc512x_psc_spi, the variable 'irq' is declared as an unsigned int. The comparison of variable 'irq' with signed int operand is incorrect. Also, the return value from the call to platform_get_irq(pdev,0) is int and it is assigned to an unsigned int variable 'irq', thus redeclaring the type of variable 'irq' to signed int. This fixes warning such as: drivers/spi/spi-mpc512x-psc.c:493:5-13: WARNING: Unsigned expression compared with zero: mps -> irq < 0 --- drivers/spi/spi-mpc512x-psc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
