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