Subject: [BUG] staging: r8188eu: driver stopped working with commit ("staging: r8188eu: add check for kzalloc")

Hi all,

The driver does not work anymore on my system. In dmesg there is:

"r8188eu 1-4:1.0: _rtw_init_xmit_priv failed"

I bisected it to commit f94b47c6bde ("staging: r8188eu: add check for 
kzalloc").

~/kernels/staging> git bisect bad
f94b47c6bde624d6c07f43054087607c52054a95 is the first bad commit

At the moment I have no time to look further into it.

regards,
Michael
