Hello Everyone,
I have a hardware(Noise processing chip) for which I am
writing the driver.Is it a good idea to download the
firmware in probe function by spawing kthread?I can't download
the firmware using request_firmware api as this hardware
is required during bootup for boot-up sound and request_firmware
is out of question because of no support in user-space.
Am i missing something?I am bit concerned about boot-up time
as well.
Please help me.

You could build it into the kernel, see CONFIG_EXTRA_FIRMWARE Kconfig
help for this.

You can also put it into intramfs and use usual request_firmware call.
