Thanks for your kind reminder. Here's v2, providing From: authorship lines in five patches (04 to 08). No logical change in the patches. --- 8< --- V2: provide missing authorship From: lines in five patches (04 to 08) Here are sh-sci serial driver fixes that have been cooking for months privately on my end: * rework console PM with the help of serial-core's uart_change_pm() * provide missing piece in SCIFB support (from Yoshii-san) * address console write function vs. SMP lockup issue and so on. Comments and suggestions are welcome. Build tested with vanilla v3.6, but not boot- nor PM-tested with newer kernels after v3.4. Anyone with can-sleep shmobile systems, please give it try.
