Subject: Re: [PATCH] tty/serial: Skip 'NULL' char after console break when sysrq enabled

> When sysrq is triggered from console, serial driver for SUN hypervisor
> console receives a console break and enables the sysrq. It expects a valid
> sysrq char following with break. Meanwhile if driver receives 'NULL'
> ASCII char then it disables sysrq and sysrq handler will never be invoked.

> This fix skips calling uart sysrq handler when 'NULL' is received while
