Subject: rt2x00: rt2800lib: fix VGC adjustment for RT5592
From: Gabor Juhos <juhosg@xxxxxxxxxxx>
commit 0beb1bbf19c72f17809e42b8f33522a55c2cc18c upstream.
In commit 3d81535ea5940446510a8a5cee1c6ad23c90c753
(rt2800: 5592: add chip specific vgc calculations)
the rt2800_link_tuner function has been modified to
adjust VGC level for the RT5592 chipset.
On the RT5592 chipset, the VGC level must be adjusted
only if rssi is greater than -65. However the current
code adjusts the VGC value by 0x10 regardless of the
actual chipset if the rssi value is between -80 and
-65.
Fix the broken behaviour by reordering the if-else
statements.
