video: fbdev: pvr2fb: remove unnecessary comparison of unsigned integer with < 0

2019-08-19T13:52:23Z

There is no need to compare *var->xoffset* or *var->yoffset* with < 0 because such variables are of type unsigned, making it impossible to hold a negative value. Fix this by removing such comparisons. Addresses-Coverity-ID: 1451964 ("Unsigned compared against 0") Signed-off-by: Gustavo A. R.

video: fbdev: don't print error message on framebuffer_alloc() failure

2019-06-28T10:30:08Z

framebuffer_alloc() can fail only on kzalloc() memory allocation failure and since kzalloc() will print error message in such case we can omit printing extra error message in drivers (which BTW is what the majority of framebuffer_alloc() users is doing already).

video: fbdev: pvr2fb: fix link error for pvr2fb_pci_exit

2019-06-21T13:13:13Z

When the driver is built-in for PCI, we reference the exit function after discarding it: `pvr2fb_pci_exit' referenced in section `.ref.data' of drivers/video/fbdev/pvr2fb.o: defined in discarded section `.exit.text' of drivers/video/fbdev/pvr2fb.o Just remove the __exit annotation as the easiest workaround. Also apply the same workaround for pvr2fb_dc_exit().

video: fbdev: pvr2fb: add COMPILE_TEST support

2019-06-07T12:38:07Z

Add COMPILE_TEST support to pvr2fb driver for better compile testing coverage. While at it: - mark pvr2fb_interrupt() and pvr2fb_common_init() with __maybe_unused tag (to silence build warnings when !SH_DREAMCAST) - convert mmio_base in struct pvr2fb_par to 'void __iomem *' from 'unsigned long' (needed to silence build warnings on ARM). - split pvr2_get_param() on pvr2_get_param_name() and pvr2_get_param_val() (needed to silence build warnings on x86).

mm/gup: change GUP fast to use flags rather than a write 'bool'

2019-05-14T16:47:46Z

To facilitate additional options to get_user_pages_fast() change the singular write parameter to be gup_flags. This patch does not change any functionality. New functionality will follow in subsequent patches. Some of the get_user_pages_fast() call sites were unchanged because they already passed FOLL_WRITE or 0 for the write parameter. NOTE: It was suggested to change the ordering of the get_user_pages_fast() arguments to ensure that callers were converted. This breaks the current GUP call site convention of having the returned pages be the final parameter. So the suggestion was rejected.
