From: David Matlack @ 2015-05-12 3:40 UTC (permalink / raw)
To: gregkh; +Cc: liodot, charrer, linux-kernel, devel, David Matlack
curaddrupper caches the last written upper 32-bits of a dma address
(the device has one register for the upper 32-bits of all dma
address registers). The problem is, not every dma address write
checks and sets curaddrupper. This causes the driver to occasionally
not write the upper 32-bits of a dma address to the device when it
really should.
I've seen this manifest particularly when the driver is trying to
read config data from the device (RCONFIG) in order to checksum the
device's eeprom. Since the device writes its config data to the
wrong DMA address the driver reads 0 as the eeprom size and the
eeprom checksum fails.
This patch fixes the issue by removing curaddrupper and always
writing the upper 32-bits of dma addresses.

It's easy for me to imagine that big shared "flags" variable in the
original code is racy so it might introduce a bugfix. :)
Nice improvement.
