Subject: [media] siano: remove the bogus firmware lookup code
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e584f9d61ea0aefa81ddd3faf53100536ba4057e;p=linux-beck.git

[media] siano: remove the bogus firmware lookup code

There is an special lookup code that is called when
SMS_BOARD_UNKNOWN. The logic there is bogus and will cause
an oops, as .type is SMS_UNKNOWN_TYPE (-1).
As the code would do:
	return smscore_fw_lkup[type][mode];
That would mean that it would try to go past the
smscore_fw_lkup table.
So, just remove that bogus code, simplifying the logic.
