Hi Kai-Heng, I finished testing this patch it's working fine, re-plug card many time don't see the issue reproduce I think this patch can fix the problem thank you Tested-by: Ricky Wu <ricky_wu@realtek.com> > Ricky, > > On Tue, Sep 26, 2023 at 11:04 PM Ulf Hansson <ulf.hansson@linaro.org> > wrote: > > > > On Thu, 14 Sept 2023 at 16:47, Ulf Hansson <ulf.hansson@linaro.org> wrote: > > > > > > On Wed, 6 Sept 2023 at 10:03, Ricky WU <ricky_wu@realtek.com> wrote: > > > > > > > > an error occurs on insert SD7.0 card. > > > > The pci slot of rtsx_pci will Link Down when the SD7.0 card > > > > inserted, but the rtsx_pci not exit from runtime_idle at that > > > > time, then do the power_saving function to access the wrong > > > > resource > > > > > > > > Fixes: 597568e8df04 ("misc: rtsx: Rework runtime power management > > > > flow") > > > > Cc: Kai-Heng Feng <kai.heng.feng@canonical.com> > > > > Signed-off-by: Ricky Wu <ricky_wu@realtek.com> > > > > > > Applied for fixes, thanks! > > > > This was not ready to be applied, my bad!
