Subject: [PATCH 4/9] tty: n_gsm: fix unneeded initialization of ret in gsm_dlci_config

From: Daniel Starke <daniel.starke@...mens.com>

The variable 'ret' is not used before assignment from gsm_activate_mux().
Still it gets initialized to zero at declaration.

Fix this as remarked in the link below by removing the initialization.

Fixes: edd5f60c3400 ("tty: n_gsm: fix mux activation issues in gsm_config()")
Link: https://lore.kernel.org/all/b42bc4d1-cc9d-d115-c981-aaa053bdc59f@kernel.org/
