Subject: [034/129] ath9k_hw: Fix EEPROM uncompress block reading on AR9003

2.6.35-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Luis R. Rodriguez <lrodriguez@...eros.com>

commit 803288e61e346ba367373bc7d5eeb6e11c81a33c upstream.

The EEPROM is compressed on AR9003, upon decompression
the wrong upper limit was being used for the block which
prevented the 5 GHz CTL indexes from being used, which are
stored towards the end of the EEPROM block. This fix allows
the actual intended regulatory limits to be used on AR9003
hardware.
