Subject: [patch 3/4] media: au0828: Consolidate dmesg output
Date: Tue, 13 Oct 2020 16:26:19 +0200
Message-ID: <20201013143731.859749817@linutronix.de> (raw)
In-Reply-To: <20201013142616.118697527@linutronix.de>

The memory allocations in au0828_init_isoc() happen all in task context
with GFP_KERNEL. Therefore a printk() trying to deduce whether this is
called from task or interrupt context is pretty useless.

Convert it to au0828_isocdbg() as the other one in that function and for
completeness sake add one for the URB allocation as well.
