From: Sarangdhar Joshi Date: Tue, 24 Jan 2017 23:13:00 +0000 (-0800) Subject: remoteproc: Reduce asynchronous request_firmware to auto-boot only X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7a20c64ddb3deeb08bbe1ca8e9bcafd3241a5e0e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git remoteproc: Reduce asynchronous request_firmware to auto-boot only The rproc_add_virtio_devices() requests firmware asynchronously and triggers boot if the auto_boot flag is set. However, this asynchronous call seems to be redundant for non auto-boot scenario since the rproc_boot() would call request_firmware() anyways. Move the auto_boot check to rproc_add() so that a redundant call to _request_firmware can be avoided for non auto-boot case.
