Subject: [PATCH 2/2] ASoC: s3c24xx: use const snd_soc_component_driver pointer
Date: Mon, 25 Jan 2016 18:07:33 +0100	[thread overview]
Message-ID: <1453741678-1988125-2-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1453741678-1988125-1-git-send-email-arnd@arndb.de>

An older patch to convert the API in the s3c i2s driver
ended up passing a const pointer into a function that takes
a non-const pointer, so we now get a warning:

sound/soc/samsung/s3c2412-i2s.c: In function 's3c2412_iis_dev_probe':
sound/soc/samsung/s3c2412-i2s.c:172:9: error: passing argument 3 of 's3c_i2sv2_register_component' discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]

However, the s3c_i2sv2_register_component() function again
passes the pointer into another function taking a const, so
we just need to change its prototype.

Fixes: eca3b01d0885 ("ASoC: switch over to use snd_soc_register_component() on s3c i2s")
