Hi,
I seem to have found a bug in the USB audio gadget driver
(drivers/usb/gadget/f_audio). When running the audio gadget module on
an omap3-based device it was crashing when plugged into the USB host.
This is seemingly because as_out_ep_desc, which is marked as
__initdata, is referenced at gadget enumeration time in the function
f_audio_set_alt, under the guise of the audio gadget's 'out_desc'
member.
I was able to fix this with the trivial patch below, although I'm not
intimately familiar with the code, so perhaps there's a more elegant
way to do this.
Best regards,
Martin Jackson
