Subject: [PATCH 2/2] staging: vc04_services: Use %p to log pointer address
Date: Tue,  7 Nov 2023 11:55:23 -0500	[thread overview]
Message-ID: <20231107165523.638555-3-umang.jain@ideasonboard.com> (raw)
In-Reply-To: <20231107165523.638555-1-umang.jain@ideasonboard.com>

Solves the following Smatch warnings:
vchiq_dev.c:1220 vchiq_release() warn: argument 7 to %lx specifier is cast from pointer

%p will print the hashed pointer to dynamic debug.
In order to print the unmodified pointer address, one can use the
`no_hash_pointers` via kernel parameters.
