    habanalabs: fix kernel pointer type · 82948e6e
    Arnd Bergmann 提交于
    All throughout the driver, normal kernel pointers are
    stored as 'u64' struct members, which is kind of silly
    and requires casting through a uintptr_t to void* every
    time they are used.
    
    There is one line that missed the intermediate uintptr_t
    case, which leads to a compiler warning:
    
    drivers/misc/habanalabs/common/command_buffer.c: In function 'hl_cb_mmap':
    drivers/misc/habanalabs/common/command_buffer.c:512:44: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
      512 |  rc = hdev->asic_funcs->cb_mmap(hdev, vma, (void *) cb->kernel_address,
    
    Rather than adding one more cast, just fix the type and
    remove all the other casts.
