The subject is still wrong (it is not a cleanup, but a fix) and the
commit message could also be improved (no need to mention the
discussion, just say why it was necessary and what you did to fix it).
Suggested text:
rtlwifi/rtl8192c[eu]: fix media status register mask
bt_msr & 0xfc will never match 0x3. Fix this by using a mask that
actually matches the available types.

(oh, and please mail me at @lekensteyn.nl for patches)
Also, when using a cover letter, you are supposed to group your changes. Not
add a single commit to each cover letter. If you made three sequential changes
for example, then you can generate your patches with:
mkdir /tmp/patches
git format-patch --cover-letter -o /tmp/patches/ HEAD~3
Then review the files in /tmp/patches/ and if you are satisfied:
git send-email --to linux-wireless@... --cc ... /tmp/patches/*
Kind regards,
