[alsa-devel] [PATCH] ALSA: usb-line6: use the same declaration as definition in header for MIDI manufacturer ID
Currently, usb-line6 module exports an array of MIDI manufacturer ID and usb-pod module uses it. However, the declaration is not the definition in common header. The difference is explicit length of array. Although compiler calculates it and everything goes well, it's better to use the same representation between definition and declaration.
This commit fills the length of array for usb-line6 module. As a small good sub-effect, this commit suppress below warnings from static analysis by sparse v0.5.0.
