Subject: ASoC: s3c24xx: use const snd_soc_component_driver pointer

From: Arnd Bergmann <[email protected]>

commit ba4bc32eaa39ba7687f0958ae90eec94da613b46 upstream.

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.
