Re: [PATCH] ARM: OMAP1: ams-delta: Fix possible use of uninitialized field

* Janusz Krzysztofik jmkrzyszt@gmail.com [181107 13:28]:

While playing with initialization order of modem device, it has been discovered that under some circumstances (early console init, I believe) its .pm() callback may be called before the uart_port->private_data pointer is initialized from plat_serial8250_port->private_data, resulting in NULL pointer dereference. Fix it by checking for uninitialized pointer before using it in modem_pm().

Applying into omap-for-v4.20/fixes thanks.
