Missing SoB. Please, read Submitting Patches documentation for understanding
what has to be done here.

Ah, seems you already aware of this issue. So, either drop Co-developed-by
(and if you wish you may give a credit in a free form inside commit message)
or make sure you get his SoB tag.

Somewhere (in the previous patch?) you want to switch to devm_mutex_init().

With

	struct devuce *dev = &client->dev;

at the top of the function makes these and more lines neater.

While changing to RCT order here, it seems you have inconsistent approach
elsewhere (in your own patches!). Please, be consistent with chosen style.
