[PATCH] USB: EHCI: don't allocate hardware periodic table atomically by default

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



ehci_mem_init() is executed one time during ehci_init() and by default
all memory allocations but ehci->periodic are done not atomically,
GFP_KERNEL is passed as flags parameter.

Do similar allocation for ehci->periodic and free some space in
coherent atomic DMA pool by default.
