Subject: [PATCH 5.15 292/917] can: bittiming: can_fixup_bittiming(): change type of tseg1 and alltseg to unsigned int

From: Marc Kleine-Budde <mkl@...gutronix.de>

[ Upstream commit e346290439609a8ac67122418ca2efbad8d0a7e7 ]

All timing calculation is done with unsigned integers, so change type
of tseg1 and alltseg to unsigned int, too.
