ARM: ux500: do not directly dereference __iomem

2023-01-07T10:15:45+00:00

commit 65b0e307a1a9193571db12910f382f84195a3d29 upstream. Sparse reports that calling add_device_randomness() on `uid` is a violation of address spaces. And indeed the next usage uses readl() properly, but that was left out when passing it toadd_device_ randomness(). So instead copy the whole thing to the stack first.

soc: qcom: Select REMAP_MMIO for ICC_BWMON driver

commit a84160fbf4f2c8c5ffa588e19ea8f92eabd7ad17 upstream. ICC_BWMON driver uses REGMAP_MMIO for accessing the hardware registers. So select the dependency in Kconfig.
