[alsa-devel] [PATCH 07/11] ALSA: hdspm - Refactor ENUMERATED_CTL_INFO into function

[Adrian Knoth]

ENUMERATED_CTL_INFO is a macro, so the binary code is generated multiple
times. To avoid code duplication, refactor the involved functionality
into a function and make ENUMERATED_CTL_INFO a call to this function.
