Running sparse (make C=1) on qmc.c raises a lot of warning such as: ... warning: incorrect type in assignment (different address spaces) expected struct cpm_buf_desc [usertype] *[noderef] __iomem bd got struct cpm_buf_desc [noderef] [usertype] __iomem *txbd_free ... Indeed, some variable were declared 'type *__iomem var' instead of 'type __iomem *var'. Use the correct declaration to remove these warnings.
