[PATCH 00/19] staging: r8188eu: migrate os_dep/xmit_linux.c

[PATCH 00/19] staging: r8188eu: migrate os_dep/xmit_linux.c

[Michael Straube]

This series moves the functions, or their functionality, from
os_dep/xmit_linux.c to the core/* part of the driver and finally
removes os_dep/xmit_linux.c and the xmit_osdep.h header.

Tested on x86_64 with Inter-Tech DMG-02.

Please apply this on top of:
[PATCH] staging: r8188eu: remove rtw_endofpktfile()

Thanks,
Michael

Hi Michael,

cannot apply your patch on top of the patch series(11),

It looks like it should fit but it does not. Have you changed something 
manual in the patch?

Thanks for your support.

Hi Philipp,

looks like you didn't apply

[PATCH] staging: r8188eu: remove rtw_endofpktfile()

first. On top of that it should work.
I mentioned that in the cover letter. ;)

[PATCH 07/19] staging: r8188eu: rename rtw_os_xmit_resource_free()

[Michael Straube]

The function rtw_os_xmit_resource_free() was moved from the os_dep
directory. It looks like the driver was originaly written to support
different operating systems. Obviously we do not need an extra 'os'
in the function name that indicates that the function is operating
system specific. Rename it to rtw_xmit_resource_free().

[Michael Straube]

The initialization to zero of the variable 'len' in rtw_pktfile_read()
is not needed. It is immediately set to another value. Remove the
initialization to zero. While at it, remove an extra space.

[PATCH 14/19] staging: r8188eu: move rtw_os_xmit_complete() to rtw_xmit.c

[Michael Straube]

Move the function rtw_os_xmit_complete() from the os_dep/xmit_linux.c
to core/rtw_xmit.c. The goal is to get rid of os_dep/xmit_linux.c in
follow up patches.

[PATCH 19/19] staging: r8188eu: remove xmit_osdep.h

[Michael Straube]

After previous cleanups the header xmit_osdep.h only contains some
structure forward declarations and extern declarations for some module
parameters. The forward declarations are not needed. We can make the
module parameters static in os_dep/os_intf.c and remove xmit_osdep.h.
