Hi,
These warnings are fixed *after* 2.6.39 (i.e., in 3.0-rc) by this git commit:
commit 3ab810f19d71f4083be44b41770bcd784ff82e51
Author: Randy Dunlap <randy.dunlap@xxxxxxxxxx>
Date: Fri Apr 1 11:24:30 2011 -0700
usb gadget: fix all Section mismatch warnings
Fix 41 occurrences of this type of Section mismatch warning
in g_mass_storage, g_serial, g_cdc, g_multi, g_nokia, g_ether, g_ffs:
(the 75 number reported earlier contained some duplicates.)
WARNING: drivers/usb/gadget/g_mass_storage.o(.text+0x687a): Section mismatch
in reference from the function fsg_bind() to the function .devinit.text:usb_ep_
autoconfig()
The function fsg_bind() references
the function __devinit usb_ep_autoconfig().
This is often because fsg_bind lacks a __devinit
annotation or the annotation of usb_ep_autoconfig is wrong.
Also remove __devinit from usb_ep_autoconfig_reset() to prevent
possible section mismatch problems with it.
and the patch is:
