Subject: [PATCH 5/6] b44: fix workarround for wap54g10
|
|
|
|
The code for the b44_wap54g10_workaround was never included, because
|
|
the config option was wrong. The nvram_get function was never in
|
|
mainline kernel, only in external OpenWrt patches.
|
|
|
|
The code should be compiled in when CONFIG_BCM47XX is selected and not
|
|
when CONFIG_SSB_DRIVER_MIPS is selected, because nvram_getenv is only
|
|
available on bcm47xx platforms and now in the mainline kernel code.
|
|
Using an include is better than a second function declaration, to fix
|
|
this when the function signature changes.
|
