[PATCH 5.5 091/119] stm class: sys-t: Fix the use of time_after()

From: Greg Kroah-Hartman
Date: Tue Mar 24 2020 - 09:25:27 EST


From: Alexander Shishkin <alexander.shishkin@xxxxxxxxxxxxxxx>

commit 283f87c0d5d32b4a5c22636adc559bca82196ed3 upstream.

The operands of time_after() are in a wrong order in both instances in
the sys-t driver. Fix that.
