[PATCH 5/5] rtlwifi: rtl8192cu: Fix value set in descriptor

[PATCH 5/5] rtlwifi: rtl8192cu: Fix value set in descriptor

[Larry Finger]

In the process of converting the bit manipulation macros were converted
to use GENMASK(), the compiler reported a value too big for the field.
The offending statement was trying to write 0x100 into a 5-bit field.
An accompaning comment says to set bit 3, thus the code is changed
appropriately.

This error has been in the driver since its initial submission.

Fixes: 29d00a3e46bb ("rtlwifi: rtl8192cu: Add routine trx")

I only see patch 5 on patchwork, what happened to patches 1-4?

I pulled them at the last minute, but forgot to rename the subject. Please apply 
that fix alone. The others will follow when I get time; however, they are code 
improvements. Only this one was a code fix.

Ok, I was just worried if patchwork had lost of them somehow.
