Since this caused regressions in -next last time, could you describe how
this was tested, and on what platforms?

I have tested this on arm64 board((U6_16550A)),PowerPC P5040
board(16550A)), x86-64 (haswell(ST16650V2),  Rangeley(16550A)) board.
This patch will modify only for the 8250 based serial devices.

Test Case : Booting Multiple times, suspend-resume.

Thanks,
