Subject: fbdev: fsl-diu-fb: Fix sparse warning due to virt_to_phys() prototype change
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=75dda3f04ae7725b028b7267e49cd0b7b98ffe19;p=linux.git
fbdev: fsl-diu-fb: Fix sparse warning due to virt_to_phys() prototype change
Explicitly cast __iomem pointer to const void* with __force to fix the
following warning:
incorrect type in argument 1 (different address spaces)
expected void const volatile *address
got char [noderef] __iomem *screen_base
