Subject: [PATCH] gpio: drop devm_gpio_chip_match()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commit 48207d7595d2 ("gpio: drop devm_gpiochip_remove()") dropped the
last user of drop devm_gpio_chip_match(), causing a defined but not used
compilation warning. Fix it by removing the function.
