Subject: video: fbdev: i740fb: use memset_io() to clear screen
Git-commit: 12acdbd7ca7d8b3ac0f55d8069f52c223d8d23fd
Patch-mainline: v5.18-rc5
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
sparse complains that using memset() on __iomem pointer is wrong:
incorrect type in argument 1 (different address spaces)
Use memset_io() to clear screen instead.
Tested on real i740 cards.
