From 9e1c785f13e0ed11ad0dade9b63fb6012df81b71 Mon Sep 17 00:00:00 2001 From: Tong Zhang Date: Thu, 18 Mar 2021 23:47:52 -0400 Subject: [PATCH] staging: comedi: das800: fix request_irq() warn 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() Suggested-by: Ian Abbott Reviewed-by: Ian Abbott Signed-off-by: Tong Zhang Link: https://lore.kernel.org/r/20210319034753.435811-1-ztong0001@gmail.com Signed-off-by: Greg Kroah-Hartman --- drivers/staging/comedi/drivers/das800.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/staging/comedi/drivers/das800.c b/drivers/staging/comedi/drivers/das800.c index 2881808d6606..bc08324f422f 100644 --- a/drivers/staging/comedi/drivers/das800.c +++ b/drivers/staging/comedi/drivers/das800.c @@ -668,7 +668,7 @@ static int das800_attach(struct comedi_device *dev, struct comedi_devconfig *it) dev->board_name = board->name; if (irq > 1 && irq <= 7) { - ret = request_irq(irq, das800_interrupt, 0, dev->board_name, + ret = request_irq(irq, das800_interrupt, 0, "das800", dev); if (ret == 0) dev->irq = irq;
