Hello everyone,
I'm resending my earlier patchsets with two changes.
First of all, there was a tiny coding style bug in one of the patches
(reported by Sergei Shtylyov).
Second of all, David has shown some concerns about overcomplicating
the g_multi driver by introducing several Kconfig options. I assumed
he knows better and so excluded this particular patch from the set.
The other patch modifying the g_multi is however legitimate in my
opinion as it clears the code and fixes some section mismatch
warnings.
The whole patchset introduces several improvements to USB gadgets,
functions, etc.:
Michal Nazarewicz (7):
USB: gadget: g_mass_storage: static data instead of dynamic
allocation
A micro optimisation preventing a kmalloc call() which would otherwise
be always called at the very beginning for the same area size.
This was submitted previously but Greg did not included it in his
quilt tree (unless I overlooked something) so I'll posting it again
for completeness. Sorry if that creates confusion.
In my opinion this is worth including as it simplifies the code a bit
and removes the call to kmalloc/kfree (hidden in fsg_common_init)
which in my opinion is a good thing as well.
Note, that the next patch won't apply without this one -- conflict is
trivial to solve though.
USB: gadget: f_mass_storage: fsg_add() renamed to fsg_bind_config()
USB: gadget: f_fs: functionfs_add() renamed to
functionfs_bind_config()
All other functions use foo_bind_config() to add function to USB
configuration so changed the names for mass storage and FunctionFS as
well.
The inconstancy apparent in multifunction gadgets stroke me for quite
some time now. I was always reluctant to submit patch thinking that
it would be just stupid name change but finally couldn't stand it. ;)
In case of mass storage the old (fsg_add()) function is still
available but marked deprecated. In case of FFS the old
(functionfs_add()) function has been removed.
USB: gadget: composite: usb_string_ids_*() functions added
USB: gadget: f_fs: use usb_string_ids_n()
usb_string_ids_n() and usb_string_ids_tab() functions added for batch
sting IDs requests.
USB: gadget: g_multi: code clean up and refactoring
USB: gadget: g_multi: added documentation and INF files
g_multi clean up, fixes, etc. Also, the last patch includes a bit of
documentation for g_multi and an INF file tested with Windows XP SP3.
Hopefully, someone will find it useful.
