4Subject: [PATCH 190/202] ssb: sprom fix some sizes / signedness
5
6Some parts of the sprom struct are bigger than needed.
7The leddc and maxpwr values are just 8 bit long and not 16.
8rxpo2g and rxpo5g are signed
9antenna_gain is unsigned
10
11I got these information for the open source part of the Braodcom SDK
12covering sprom version 1 to 9. rxpo2g contained a negative number on my
13bcm5354 based device, this cased an error and Broadcom SDK says this is
14signed.
15
16I was unable to find any reverences to antenna_gain.ghz5 in the
17Broadcom SDK.
