Subject: [PATCH AUTOSEL 5.4 14/26] s390/qeth: vnicc Fix init to default
Date: Fri, 10 Jan 2020 17:05:07 -0500 [thread overview]
Message-ID: <20200110220519.28250-9-sashal@kernel.org> (raw)
In-Reply-To: <20200110220519.28250-1-sashal@kernel.org>
From: Alexandra Winter <wintera@linux.ibm.com>
[ Upstream commit d1b9ae1864fc3c000e0eb4af8482d78c63e0915a ]
During vnicc_init wanted_char should be compared to cur_char and not
to QETH_VNICC_DEFAULT. Without this patch there is no way to enforce
the default values as desired values.
Note, that it is expected, that a card comes online with default values.
This patch was tested with private card firmware.
Fixes: caa1f0b10d18 ("s390/qeth: add VNICC enable/disable support")
