[PATCH 0/3] TTY improve n_gsm support

From: Gregory CLEMENT

Hello,

This series if patch improve n_gms support especially with TELIT
LE910. However the fix should benefit to any modem supporting cmux.

The first patch is just about improving debugging output.

The second one removes a tty optimization which make the LE910 hang.

The last one fixes an issue observed on the LE910 but should benefit
to all the modem. We observed that pretty quickly the transfer done
using the virtual tty were blocked. We found that it was due of a
wakeup to the real tty. Without this fix, the real tty wait for
indefinitely.
