From c9dd94385d48529da7a2eb88963883b8080e83d9 Mon Sep 17 00:00:00 2001 From: Mathias Nyman Date: Thu, 23 Jul 2020 17:45:08 +0300 Subject: [PATCH] xhci: dbc: Remove dbc_dma_alloc_coherent() wrapper dbc_dma_alloc_coherent() takes struct xhci_hcd pointer as an parameter, but does nothing more than calls dma_alloc_coherent(). Remove it and call dma_alloc_coherent() directly instead. No functional changes This change helps decoupling xhci and DbC Signed-off-by: Mathias Nyman Link: https://lore.kernel.org/r/20200723144530.9992-6-mathias.nyman@linux.intel.com Signed-off-by: Greg Kroah-Hartman --- drivers/usb/host/xhci-dbgcap.c | 17 ++--------------- 1 file changed, 2 insertions(+), 15 deletions(-) diff --git a/drivers/usb/host/xhci-dbgcap.c b/drivers/usb/host/xhci-dbgcap.c index 138b0c994ad2..e8a2cbda135c 100644 --- a/drivers/usb/host/xhci-dbgcap.c +++ b/drivers/usb/host/xhci-dbgcap.c @@ -14,17 +14,6 @@ #include "xhci-trace.h" #include "xhci-dbgcap.h" -static inline void * -dbc_dma_alloc_coherent(struct xhci_hcd *xhci, size_t size, - dma_addr_t *dma_handle, gfp_t flags) -{ - void *vaddr; - - vaddr = dma_alloc_coherent(xhci_to_hcd(xhci)->self.sysdev, - size, dma_handle, flags); - return vaddr; -} - static inline void dbc_dma_free_coherent(struct xhci_hcd *xhci, size_t size, void *cpu_addr, dma_addr_t dma_handle) @@ -426,10 +415,8 @@ static int xhci_dbc_mem_init(struct xhci_hcd *xhci, gfp_t flags) /* Allocate the string table: */ dbc->string_size = sizeof(struct dbc_str_descs); - dbc->string = dbc_dma_alloc_coherent(xhci, - dbc->string_size, - &dbc->string_dma, - flags); + dbc->string = dma_alloc_coherent(dev, dbc->string_size, + &dbc->string_dma, flags); if (!dbc->string) goto string_fail;
