Stefan Dösinger 082d9e263a wifi: brcmfmac: Check the return value of of_property_read_string_index() 
Somewhen between 6.10 and 6.11 the driver started to crash on my
MacBookPro14,3. The property doesn't exist and 'tmp' remains
uninitialized, so we pass a random pointer to devm_kstrdup().

The crash I am getting looks like this:

BUG: unable to handle page fault for address: 00007f033c669379
