90accd0b47 net: wirelesse: wcn36xx: pull allocation outside of critical section
Commit [3469adb3: fix potential NULL pointer dereference] introduced
a check of msg_ind allocation, but omitted allocation of msg_ind->msg.
Moreover, it introduced two if statements, which looked a bit clunky.

This commit moves allocation code outside of the critical section so
there's no need to dance around mutex_unlock, and adds the missing
allocation check.

fa643ae2ce wcn36xx: enable the beaconing in mesh mode
Enable the beaconing in wnc36xx by tweaking the tim offset and
force the use of AP-style beaconing. Otherwise, beaconing is not
working. The tim offset is set to 256. Otherwise, this will
overwrite mesh beacon submitted by mac80211.

42bc702e76 wcn36xx: set self STA default HT parameters
These default HT parameters are required for self STA entry.
In example, set the HT capable of self STA entry for bss
configuration in mesh allows the MCS rate to be used. Otherwise,
only legacy rate will be used.

3469adb36c net: wireless: wcn36xx: fix potential NULL pointer dereference
If kmalloc fails wcn36xx_smd_rsp_process will attempt to dereference
a NULL pointer.  There might be a better error recovery then just
printing an error, but printing an error message is better then the
current behaviour.

50d60c6322 wcn36xx: fix coccinelle warnings
drivers/net/wireless/ath/wcn36xx/debug.c:27:11-31: WARNING opportunity for simple_open, see also structure on line 106
/c/kernel-tests/src/i386/drivers/net/wireless/ath/wcn36xx/debug.c:27:11-31: WARNING opportunity for simple_open, see also structure on line 148

 This removes an open coded simple_open() function
 and replaces file operations references to the function
 with simple_open() instead.
