Subject: [PATCH v2] staging: comedi: das800: fix request_irq() warn
Date: Thu, 18 Mar 2021 23:47:52 -0400 [thread overview]
Message-ID: <20210319034753.435811-1-ztong0001@gmail.com> (raw)
In-Reply-To: <8c65b02e-4315-153f-de2c-153862f195be@mev.co.uk>
request_irq() won't accept a name which contains slash so we need to
replace it with something else -- otherwise it will throw 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()
