2020-07-29usb: xhci: Fix ASMedia ASM1142 DMA addressingForest Crossman1-1/+3
I've confirmed that the ASMedia ASM1142 has the same problem as the ASM2142/ASM3142, in that it too reports that it supports 64-bit DMA addresses when in fact it does not. As with the ASM2142/ASM3142, this can cause problems on systems where the upper bits matter, and adding the XHCI_NO_64BIT_SUPPORT quirk completely fixes the issue.

2020-07-29usb: typec: tcpm: Fix AB BA lock inversion between tcpm code and the ↵Hans de Goede1-0/+30
alt-mode drivers When we receive a PD data packet which ends up being for the alt-mode driver we have the following lock order: 1. tcpm_pd_rx_handler take the tcpm-port lock 2. We call into the alt-mode driver which takes the alt-mode's lock And when the alt-mode driver initiates communication we have the following lock order: 3. alt-mode driver takes the alt-mode's lock 4. alt-mode driver calls tcpm_altmode_enter which takes the tcpm-port lock This is a classic AB BA lock inversion issue. With the refactoring of tcpm_handle_vdm_request() done before this patch, we don't rely on, or need to make changes to the tcpm-port data by the time we make call 2. from above. All data to be passed to the alt-mode driver sits on our stack at this point, and thus does not need locking. So after the refactoring we can simply fix this by releasing the tcpm-port lock before calling into the alt-mode driver.
