ALSA: pci: constify local structures
For structure types defined in the same file or local header files, find top-level static structure declarations that have the following properties: 1. Never reassigned. 2. Address never taken 3. Not passed to a top-level macro call 4. No pointer or array-typed field passed to a function or stored in a variable. Declare structures having all of these properties as const. Done using Coccinelle. Based on a suggestion by Joe Perches <joe@perches.com>. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Takashi Iwai <tiwai@suse.de>
