Fredrik Noring f8c63edfd7 USB: Fix incorrect DMA allocations for local memory pool drivers ... Fix commit 7b81cb6bdd ("usb: add a HCD_DMA flag instead of guestimating DMA capabilities") where local memory USB drivers erroneously allocate DMA memory instead of pool memory, causing OHCI Unrecoverable Error, disabled HC died; cleaning up The order between hcd_uses_dma() and hcd->localmem_pool is now arranged as in hcd_buffer_alloc() and hcd_buffer_free(), with the test for hcd->localmem_pool placed first. As an alternative, one might consider adjusting hcd_uses_dma() with static inline bool hcd_uses_dma(struct usb_hcd *hcd) { - return IS_ENABLED(CONFIG_HAS_DMA) && (hcd->driver->flags & HCD_DMA); + return IS_ENABLED(CONFIG_HAS_DMA) && + (hcd->driver->flags & HCD_DMA) && + (hcd->localmem_pool == NULL); } One can also consider unsetting HCD_DMA for local memory pool drivers.
