Subject: [PATCH] can: bittiming: can_fixup_bittiming(): change type of tseg1 and alltseg to unsigned int
Git-commit: e346290439609a8ac67122418ca2efbad8d0a7e7
Patch-mainline: v5.16-rc1
References: stable-5.14.19
[ Upstream commit e346290439609a8ac67122418ca2efbad8d0a7e7 ]
All timing calculation is done with unsigned integers, so change type
of tseg1 and alltseg to unsigned int, too.
