Hi Maxim,

I think the patch message can be improved, like:

"Commit 421c8d9a20da ("usb: gadget: f_mass_storage: forced_eject attribute")
adds force_eject entry to config-usb-gadget-mass-storage table. However, the table border for attribute name is short by one =, which triggers Sphinx warning.

Extend the border to cover the now-longest entry."

Thanks.
