Subject: [PATCH 4/4] platform/chrome: cros_ec_typec: Update mux flags during partner removal

In cros_typec_remove_partner(), we call
cros_typec_usb_disconnect_state() which sets the switches/muxes to be in
a disconnected state. This also happens in cros_typec_configure_mux().
However, unlike there, here the mux_flags variable hasn't been updated
to reflect that a disconnection has occurred. Update the flag here
accordingly.

Hi Tzung-Bi,

Thanks for reviewing the series.

Again, "update" is fine. Please see:
https://www.kernel.org/doc/html/latest/process/submitting-patches.html#describe-your-changes

Quoting from the above: " Describe your changes in imperative mood,"

So, imperative usage is actually preferred, and "updates/makes" is discouraged.

(I grabbed an older version of the documentation in my other replies,
but the description is the same).

Thanks!

It is fine (at least to me) usually.

Since you would need to respin the series anyway, s/Update/Updates/.

Ack, thanks for correcting my so-long-time misunderstanding.
