Subject: [PATCH] ALSA: kunit: use const qualifier for immutable data
Date: Fri, 26 Apr 2024 08:36:53 +0900 [thread overview]
Message-ID: <20240425233653.218434-1-o-takashi@sakamocchi.jp> (raw)
Some data for testing is immutable. In the case, the const qualifier is
available for any loader to place it to read-only segment.
Fixes: 3e39acf56ede ("ALSA: core: Add sound core KUnit test")
Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp>
