Subject: [PATCH AUTOSEL 5.10 27/39] staging: comedi: cb_pcidas64: fix request_irq() warn
Date: Thu, 25 Mar 2021 07:25:46 -0400	[thread overview]
Message-ID: <20210325112558.1927423-27-sashal@kernel.org> (raw)
In-Reply-To: <20210325112558.1927423-1-sashal@kernel.org>

From: Tong Zhang <ztong0001@gmail.com>

[ Upstream commit d2d106fe3badfc3bf0dd3899d1c3f210c7203eab ]

request_irq() wont accept a name which contains slash so we need to
repalce it with something else -- otherwise it will trigger a warning
and the entry in /proc/irq/ will not be created
since the .name might be used by userspace and we don't want to break
userspace, so we are changing the parameters passed to request_irq()

[    1.565966] name 'pci-das6402/16'
