* gpu: nvgpu: Suppress error msg from VBIOS overlayTerje Bergstrom2016-10-09
| | | | | | | | | | | | | | | | | | | | Suppress error message when nvgpu tries to load VBIOS overlay, but one is not found. This situation is normal. This is done by moving gk20a_request_firmware() to be nvgpu generic function nvgpu_request_firmware(), and adding a NO_WARN flag to it. Introduce also a NO_SOC flag to suppress attempt to load firmware from SoC specific directory in addition to the chip specific directory. Use it for dGPU firmware files.
