Subject: [PATCH -mmotm] staging/easycap: fix build when SND is not enabled

From: Randy Dunlap <randy.dunlap@...cle.com>

Fix easycap build when CONFIG_SOUND is enabled but CONFIG_SND is
not enabled.

These functions are only built when CONFIG_SND is enabled, so the
driver should depend on SND.
This means that having SND enabled is required for the (obsolete)
EASYCAP_OSS config option.
