Subject: [PATCH 190/202] ssb: sprom fix some sizes / signedness
Some parts of the sprom struct are bigger than needed.
The leddc and maxpwr values are just 8 bit long and not 16.
rxpo2g and rxpo5g are signed
antenna_gain is unsigned
I got these information for the open source part of the Braodcom SDK
covering sprom version 1 to 9. rxpo2g contained a negative number on my
bcm5354 based device, this cased an error and Broadcom SDK says this is
signed.
I was unable to find any reverences to antenna_gain.ghz5 in the
Broadcom SDK.
