Hi all
Have these warning messages when compiling kernel.
Anyone know what's wrong?

Hi all
I am new in PCI and now working on MSI support on our PCIe host
driver. I have an endpoint driver requests for a MSI interrupt. When
the endpoint driver try to free the interrupt, it cause the kernel
BUG_ON() message is printed out.
The software flow:
Endpoint driver --> pci_disable_msi

Hi all
Do we have hardware mutex common framework available in kernel? I
can't find in drivers/, but, I found there is a hardware spinlock
framework under drivers/hwspinlock.
I believe the spinlock and mutex should have different framework.
Please correct me if wrong.
