[PATCH] net: b44: Remove the unused function __b44_cam_read()

[Jiapeng Chong]

The function __b44_cam_read() is defined in the b44.c file, but not called
elsewhere, so remove this unused function.

drivers/net/ethernet/broadcom/b44.c:199:20: warning: unused function '__b44_cam_read'.

Thanks,

This seems to have been the case since '__b44_cam_read' was
created via some refactoring in 2007 by

753f492093da ("[B44]: port to native ssb support")

But I'm not sure this warrants a fixes tag.
