Subject: [PATCH AUTOSEL 5.3 05/99] rt2x00: initialize last_reset

From: Stanislaw Gruszka <sgruszka@...hat.com>

[ Upstream commit c91a9cfe9f6d136172a52ff6e01b3f83ba850c19 ]

Initialize last_reset variable to INITIAL_JIFFIES, otherwise it is not
possible to test H/W reset for first 5 minutes of system run.

Fixes: e403fa31ed71 ("rt2x00: add restart hw")
