From mboxrd@z Thu Jan 1 00:00:00 1970 From: William Breathitt Gray Subject: [PATCH 0/2] Fix port memory offsets for IDIO series drivers Date: Wed, 18 Apr 2018 08:52:39 -0400 Message-ID: Return-path: Sender: linux-kernel-owner@vger.kernel.org To: linus.walleij@linaro.org Cc: linux-gpio@vger.kernel.org, linux-kernel@vger.kernel.org, William Breathitt Gray List-Id: linux-gpio@vger.kernel.org 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.
