Subject: [PATCH 0/3] usb: gadget: Add a prefix to log messages

I met some log as below:
[  581.262476] read descriptors
[  581.265558] bcdVersion must be 0x0100, stored in Little Endian order...

To be honest, if I'm not familiar with the usb gadget framework, I dunno
which component is complaining. Add a prefix to log messages, so the
above messages will be look as below:

[  581.262476] usb_f_fs: read descriptors
[  581.265558] usb_f_fs: bcdVersion must be 0x0100, stored in Little Endian order...

Then solve similar issues for f_mass_storage and f_tcm.
