From bba3a87e982ad5992e776ca1fc409326915d6b44 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 2 Dec 2013 15:38:16 +0100 Subject: [PATCH] firmware: Introduce request_firmware_direct() When CONFIG_FW_LOADER_USER_HELPER is set, request_firmware() falls back to the usermode helper for loading via udev when the direct loading fails. But the recent udev takes way too long timeout (60 seconds) for non-existing firmware. This is unacceptable for the drivers like microcode loader where they load firmwares optionally, i.e. it's no error even if no requested file exists. This patch provides a new helper function, request_firmware_direct(). It behaves as same as request_firmware() except for that it doesn't fall back to usermode helper but returns an error immediately if the f/w can't be loaded directly in kernel. Without CONFIG_FW_LOADER_USER_HELPER=y, request_firmware_direct() is just an alias of request_firmware(), due to obvious reason.
