in [Kernel]
|
Prev: [PATCHv6 5/7] USB: gadget: mass_storage: moved strings handling code to composite
Next: [PATCHv6 4/7] USB: gadget: composite: Better string override handling
From: Michal Nazarewicz on 5 Aug 2010 06:30 The "nofua" attribute is used in the File-Storage Gadget but the functions handling it are defined in storage_common.c (which may be not a bad thing if anyone will want to port tho "nofua" attribute to mass storage function) which causes the following warnings: drivers/usb/gadget/storage_common.c:718: \ warning: 'fsg_show_nofua' defined but not used drivers/usb/gadget/storage_common.c:782: \ warning: 'fsg_store_nofua' defined but not used Adding __maybe_unused fixes this issue.
