[PATCH] gpio: pca953x: variable 'id' was used twice

[PATCH] gpio: pca953x: variable 'id' was used twice

[Wolfram Sang]

sparse  rightfully said:

drivers/gpio/gpio-pca953x.c:771:45: warning: symbol 'id' shadows an earlier one
drivers/gpio/gpio-pca953x.c:742:36: originally declared here

So, name them explicitly 'i2c_id' and 'acpi_id' to avoid any confusion.

Compile tested only. Found while doing review of another patch touching this
driver.
