There is no matching spi_get_drvdata() call in the driver, so there is no
need to do spi_set_drvdata(). This looks like it probably was copied from a
driver that used both spi_set_drvdata() & spi_get_drvdata().

While above luckily (*) okay it may not always be the case.

*) it can be paired with dev_get_drvdata() which is usual for PM callbacks.

I applied this patch. I wasn't sure exactly how you want the commit
message to be changed - it sounds pretty clear to me so I took it.

For example, by adding " or dev_get_drvdata()" to the end.
