Subject: [PATCH] ucb1400_ts depends SND_AC97_BUS

From: Randy Dunlap <>

This driver is an AC97 codec according to its help text.
However, if SOUND is disabled, the "select SND_AC97_BUS"
still inserts that into the .config file:

# Sound
# CONFIG_SOUND is not set

Even if the config software followed dependency chains on selects,
we should try to limit usage of "select" to library-type
code that is needed (e.g., CRC functions) instead of bus-type
