Subject: [alsa-devel] [PATCH 01/68] ALSA: Allow const arrays for legacy resource management helpers
Date: Sun,  5 Jan 2020 15:47:16 +0100
Message-ID: <20200105144823.29547-2-tiwai@suse.de> (raw)
In-Reply-To: <20200105144823.29547-1-tiwai@suse.de>

Declare the arrays passed to the helper functions for legacy resources
(mostly for ISA drivers) as const, so that each caller can make its
static data as const for minor optimizations, too.
