Subject: [PATCH 0/2] Fix port memory offsets for IDIO series drivers

The GPIO PCI-IDIO-16 and PCIE-IDIO-24 drivers utilize the ioread8 and
iowrite8 functions to interact with their devices' respective I/O
registers. To simplify the get_multiple/set_multiple callbacks, a local
array 'ports' is used to hold the memory address offsets of the
respective device I/O registers.

Currently the get_multiple callback in the GPIO PCI-IDIO-16 driver, and
the get_multiple/set_multiple callbacks in the GPIO PCIE-IDIO-24 driver,
incorrectly pass the memory address of the local 'ports' array elements
to the respective ioread8/iowrite8 functions when they should instead
pass the necessary device I/O register memory offset. This patch fixes
this error by supplying the correct intended memory addresses to these
functions.

  gpio: pcie-idio-24: Fix port memory offset for
    get_multiple/set_multiple callbacks
