USB: storage: make the "quirks=" module parameter writable
This patch (as1190) makes usb-storage's "quirks=" module parameter writable, so that users can add entries for their devices at runtime with no need to reboot or reload usb-storage. New codes are added for the SANE_SENSE, CAPACITY_HEURISTICS, and CAPACITY_OK flags. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
