The error handling in this function was broken and while looking at that
I noticed that the whole function was in need of cleanup. This patch
fixes the error handling, specifically
if (!p) {
visorchannel_destroy(p);
channel = NULL;
}
and does a lot of cleanup. I also verified that the called functions
returned correct errors, and that led to a change in
visor_memregion_resize(), visorchannel_destroy() and
visor_memregion_destroy().

visorbus_private.h contains code that is called from visorbus into the
visorchipset code. Now that the visorchipset code has been brought into
the visorbus directory, many of the declarations are not necessary and
can be cleaned up.
TODO: PARSER_WHICH_STRING enum only has one member used
(PARSERSTRING_NAME).
TODO: crash_obj_type appears to be unnecessary in the overall scheme of

Move visorchipset_main.c and visorchipset.h to visorbus/visorchipset.c and
visorbus/visorbus_private.h. This leaves an empty visorchipset directory
which can also be destroyed.
As a result of this patch the visorchipset init code now calls the
visorbus_init() directly. Similarily the visorchipset exit code now
cleans up by calling visorbus_exit().
No other functional changes were made.

supports sPar bus model and manages bus specific functionality. It
maintains the sysfs subtree /sys/devices/visorbus*/.It is
responsible for device creation and destruction of the devices on

These are all defined as a part of the standard and should not be
duplicated on a per-driver basis. Use the global ones and delete the
local ones.
In switching to <linux/ieee80211.h> we have to delete a local copy of
an identical struct that we prepped earlier to have identical field
names, and we add explicit include <...> where needed in order to
preserve getting a successful compile.
This isn't the totality of duplicated data removed, but it is a start.

The <linux/ieee80211.h> and this local file both have a struct of the
same name. They also have the same field sizes and generally the
same fields, as can be seen here:
~/git/linux-head$ git grep -A4 'struct ieee80211_wmm_ac_param {'
drivers/staging/rtl8192u/ieee80211/ieee80211.h:struct ieee80211_wmm_ac_param {
drivers/staging/rtl8192u/ieee80211/ieee80211.h- u8 ac_aci_acm_aifsn;
drivers/staging/rtl8192u/ieee80211/ieee80211.h- u8 ac_ecwmin_ecwmax;
drivers/staging/rtl8192u/ieee80211/ieee80211.h- u16 ac_txop_limit;
drivers/staging/rtl8192u/ieee80211/ieee80211.h-};
--
include/linux/ieee80211.h:struct ieee80211_wmm_ac_param {
include/linux/ieee80211.h- u8 aci_aifsn; /* AIFSN, ACM, ACI */
include/linux/ieee80211.h- u8 cw; /* ECWmin, ECWmax (CW = 2^ECW - 1) */
include/linux/ieee80211.h- __le16 txop_limit;
include/linux/ieee80211.h-} __packed;
~/git/linux-head$
Here we just align the local field names with the main system one. Then
we can add an include of the system one and delete the local copy in one
smooth step in a follow-on commit.
Not that the replacement:
for i in `find . -name '*.[ch]'` ; do sed -i 's/ac_aci_acm_aifsn/aci_aifsn/g' $i ; done
for i in `find . -name '*.[ch]'` ; do sed -i 's/ac_ecwmin_ecwmax/cw/g' $i ; done
for i in `find . -name '*.[ch]'` ; do sed -i 's/ac_txop_limit/txop_limit/g' $i ; done
implicitly shows that only one of the three fields is currently used.

Currently LEAP is defined to two locally but the identically named
global constant is 128 in <linux/ieee80211.h>. In order for us to
switch over to using the global value, we need to adjust the local
storage which is currently not enough to hold the larger value.
This is now consistent with the similar struct used in
drivers/net/wireless/ipw2x00/libipw.h and other drivers.
