Subject: [patch 2.6.26-rc8] gpio: pca953x (i2c) handles max7310 too

The pca953x driver can handle another 8-bit I/O expander, the
max7310.  This patch adds that chip to the list of supported IDs
in that driver, and expands the Kconfig helptext accordingly.

Signed-off-by: David Brownell <dbrownell@...rs.sourceforge.net>

Yes:  the max7310 is I2C, the max7310 is SPI.
Almost like they're trying to spread confusion...
