usb: gadget: f_uac1: Change volume name and remove alt names
This changes the UAPI to align with disussion of alt settings work. fu_name is renamed to fu_vol_name, and alt settings mode names are removed for now in favor of future work where they will be settable in subdirectories for each alt mode. discussion thread for api changes for alt mode settings: https://lore.kernel.org/linux-usb/35be4668-58d3-894a-72cf-de1afaacae45@ivitera.com/T/ Signed-off-by: Chris Wulff <crwulff@gmail.com> Link: https://lore.kernel.org/r/20240804002912.3293177-2-crwulff@gmail.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
