This was intended to be an IS_ERR() check, not a NULL check. The ep93xx_dma_of_probe() function doesn't return NULL pointers. Fixes: 4e8ad5ed845b ("dmaengine: cirrus: Convert to DT for Cirrus EP93xx") Signed-off-by:Dan Carpenter <dan.carpenter@linaro.org> Reviewed-by:

Fix raster_on_sdram0_pins used in PMX_GROUP() instead of raster_on_sdram3_pins as it should be.

The psc->div[] array has psc->num_div elements. These values come from when we call clk_hw_register_div(). It's adc_divisors and ARRAY_SIZE(adc_divisors)) and so on. So this condition needs to be >= instead of > to prevent an out of bounds read. Fixes: 9645ccc7 ("ep93xx: clock: convert in-place to COMMON_CLK") Signed-off-by:

Add compulsory device tree support to the Cirrus ep93xx ARMv4 platform. - select PINCTRL_EP93xx - select COMMON_CLK_EP93XX, as clock driver moved out of platform code - select ARCH_HAS_RESET_CONTROLLER Select ARM_ATAG_DTB_COMPAT to update device tree with information about memory passed from bootloader. We have to leave all MACH options as they are used for board checking before decomp, to turn off watchdog and ethernet DMA. Tested-by:
