Subject: [PATCH v2] dmaengine: loongson: Remove the %p pointer output
Date: Fri, 18 Sep 2026 22:17:14 +0200	[thread overview]
Message-ID: <20260918201714.eFNI3VMq@linutronix.de> (raw)

The %pK format modifier was meant for /proc kind of output, not general
printk output. Since commit ad67b74d2469d ("printk: hash addresses
printed with %p") pointers are hashed by default and the behaviour can
be controller by `hash_pointers' boot argument.
The policy on %p is to not introduce new ones. This is the only pointer
output in the driver.

Remove the pointer formating from debug output.
