[PATCH 0/2] tty: n_gsm: revert tx_mutex usage

Posted by Fedor Pchelkin 3 years, 6 months ago

As far as switching to tx_mutex turns out to have its own problems,
we suggest to revert it and to find another solution for the original
issue described in 902e02ea9385 ("tty: n_gsm: avoid call of sleeping
functions from atomic context").

We have lived with locking problems for a long time, and we really
don't want data corruption.
