[alsa-devel] [PATCH v2] ALSA: ctxfi: constify rsc ops structures

Sun Nov 8 23:40:41 CET 2015
The various rsc ops structures are never modified, so declare them as
const.
Done with the help of Coccinelle.

v2: This does the following types all at once: dao_rsc_ops, dai_rsc_ops,
amixer_rsc_ops, src_rsc_ops, srcimp_rsc_ops, rsc_ops. Most of these types
are only used in specific files, but the rsc_ops structures appear in all
of the files, so just do them all at once. This patch thus also replaces
the one with the subject "ALSA: ctxfi: constify dao and dai rsc ops structures"
