[PATCH 15/18] serial: max310x: replace ENOTSUPP with preferred EOPNOTSUPP (checkpatch)

[Hugo Villeneuve]

From: Hugo Villeneuve <hvilleneuve@xxxxxxxxxxxx>

Fixes the following checkpatch warning:

    WARNING: ENOTSUPP is not a SUSV4 error code, prefer EOPNOTSUPP

According to include/linux/errno.h, ENOTSUPP is
"Defined for the NFSv3 protocol", so replace it with preferred EOPNOTSUPP.

Similar to commit c7581a414d28 ("drm: Use EOPNOTSUPP, not ENOTSUPP").
