Subject: MIPS: pb44: Fix i2c-gpio GPIO descriptor table
From: Linus Walleij <linus.walleij@xxxxxxxxxx>
commit 326345f995a83e326fa2e01d54bfa9a6a307bd4d upstream.
I used bad names in my clumsiness when rewriting many board
files to use GPIO descriptors instead of platform data. A few
had the platform_device ID set to -1 which would indeed give
the device name "i2c-gpio".
But several had it set to >=0 which gives the names
"i2c-gpio.0", "i2c-gpio.1" ...
Fix the one affected board in the MIPS tree. Sorry.
