Subject: rockchip: adc: rockchip-saradc: use dev_read_addr_ptr
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=ac9198d1d549b516c7c27f7eaf19dd4a9b5dfbf5;p=u-boot.git

rockchip: adc: rockchip-saradc: use dev_read_addr_ptr

The fdt_addr_t and phys_addr_t size have been decoupled.
A 32bit CPU can expext 64-bit data from the device tree parser,
so use dev_read_addr_ptr in the rockchip-saradc.c file.
As we are there also streamline the error response to -EINVAL on return.
