Re: [PATCH] PCI: Do not enable async suspend for JMicron chips

[Barto]

Hello Bjorn,

in my bugreport I have already tried to add the JMicron 368 in the "if
statement" and it didn't work, check my message here :

https://bugzilla.kernel.org/show_bug.cgi?id=84861#c11

if Chuansheng has choosen a more generic way ( applying the patch to all
JMicron devices  ) it's because also because we don't know how many
JMBxxx models could be affected by this bug, tomorrow maybe one user
would create a bug report about a "JMB369" pci card who have again this
bug, and maybe on month later another user with a "JMB382", it could be
a nightmare for Chuanseng if he had to create every time a new patch for
each model of JMicron,

so for the moment the better approach for me is to disable async_suspend
for all JMBxxx JMicron, Chuanseng's patch seems reasonnable, as long as
we don't know the exact list of JMBxxx models we can assume that all
JMicron SATA/IDE are affected by this problem
