Subject: [PATCH] libertas link error due to gcc `smartness'
Some versions of gcc replace strstr() calls with a single-character `needle'
parameter by strchr() behind our back. This causes a link error if strchr() is
defined as an inline function in <asm/string.h> (e.g. on m68k):
| drivers/built-in.o: In function `libertas_parse_chan':
| linux/drivers/net/wireless/libertas/debugfs.c:209: undefined reference to `strchr'
| drivers/built-in.o: In function `libertas_parse_ssid':
| linux/drivers/net/wireless/libertas/debugfs.c:260: undefined reference to `strchr'
Avoid this by explicitly calling strchr() instead.
Also include <linux/string.h>, because this file calls lots of str*() routines.

Due to the lack of hardware, I could not test the functionality of this change.
I was just trying to compile a kernel with a much enabled as possible.

when I'm talking to journalists I just say "programmer" or something like that.
