My investigation shows that the test for an invalid length was placed after
the memcpy() call that generates this warning.

The fix is to move the test above the memcpy, and to increase the maximum
size of the IE buffer.

7245a6982d rtl8188eu: Change get_ra() to wifi_get_ra() 
Author: Giulio Benetti giulio.benetti@benettiengineering.com

In PowerPc Linux only get_ra() exists[0] and conflicts with local get_ra()
that has a completely different purpose. So let's rename local get_ra()
to wifi_get_ra() to make it different from Linux's get_ra().

The changes that were in kernel 6.0 hav been backported to 5.19.2.
Backporting these kind of changes is pointless. In 6.0, the way is
prepared to allow multiple links per connection. In 5.19, the only
one used is link 0! What is the point?

Kernel commit 51d62f2f2c50 ("cfg80211: Save the regulatory domain with a lock")
caused a lock dependency to the cfg80211 version of this driver. It is fixed by
moving the regulatory domain initialization call so that it is outside the lock
in the probe routine.
