Subject: USB: OHCI: don't allocate HCCA atomically
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4428524d8d01afae18844e73f330d2e8431f312e;p=linux-beck.git

USB: OHCI: don't allocate HCCA atomically

OHCI HCCA memory region is allocated from atomic DMA pool one time
during usb_add_hcd() and deallocated by usb_remove_hcd().

Do non-atomic allocation of OHCI HCCA and free some space in
coherent atomic DMA pool.
