Subject: [PATCH 3/3] soc: qcom: mdt_loader: add offset to request_firmware_into_buf
Date: Wed, 22 May 2019 19:51:13 -0700
Message-ID: <20190523025113.4605-4-scott.branden@broadcom.com> (raw)
In-Reply-To: <20190523025113.4605-1-scott.branden@broadcom.com>

Adjust request_firmware_into_buf API to allow for portions
of firmware file to be read into a buffer.  mdt_loader still
retricts request fo whole file read into buffer.
