usb_buffer_free和usb_buffer_alloc的編譯錯誤

Question

嗨，我在將usbtouchscreen.c編譯到內核驅動程序時出錯。 我也將usbtouchsreen.c文件附加到了帖子中。

 CC      drivers/input/touchscreen/usbtouchscreen.o
drivers/input/touchscreen/usbtouchscreen.c: In function 'usbtouch_free_buffers':
drivers/input/touchscreen/usbtouchscreen.c:856: error: implicit declaration of function 'usb_buffer_free'
drivers/input/touchscreen/usbtouchscreen.c: In function 'usbtouch_probe':
drivers/input/touchscreen/usbtouchscreen.c:890: error: implicit declaration of function 'usb_buffer_alloc'
drivers/input/touchscreen/usbtouchscreen.c:891: warning: assignment makes pointer from integer without a cast

make[2]: *** [drivers/input/touchscreen] Error 2
make[1]: *** [drivers/input] Error 2

我在此處包含了源代碼： http : //pastebin.com/GTsic7Bg

您的驅動程序是否很舊（或者對於較舊的內核而言）？ 也許您想看一下這個重命名：

https://lkml.org/lkml/2010/4/12/132

它似乎至少在最新的內核中：

http://lxr.linux.no/linux+ * / drivers / usb / core / usb.c＃L698

實際上，它似乎已經進入了2.6.34左右。
