vfio-dev/mdpy-fb: Use fbdev I/O helpers Set struct fb_ops and with FB_DEFAULT_IOMEM_OPS, fbdev's initializer for I/O memory. Sets the callbacks to the cfb_ and fb_io_ functions. Select the correct modules with Kconfig's FB_IOMEM_HELPERS token. The macro and token set the currently selected values, so there is no functional change. v3: * use _IOMEM_ in commit message v2: * updated to use _IOMEM_ tokens Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: Helge Deller <deller@gmx.de> Cc: Kirti Wankhede <kwankhede@nvidia.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230803184034.6456-48-tzimmermann@suse.de

vfio-mdev: add missing MODULE_DESCRIPTION() macros Since commit 1fffe7a34c89 ("script: modpost: emit a warning when the description is missing"), a module without a MODULE_DESCRIPTION() will result in a warning with make W=1. The following warnings are being observed in samples/vfio-mdev: WARNING: modpost: missing MODULE_DESCRIPTION() in samples/vfio-mdev/mtty.o WARNING: modpost: missing MODULE_DESCRIPTION() in samples/vfio-mdev/mdpy.o WARNING: modpost: missing MODULE_DESCRIPTION() in samples/vfio-mdev/mdpy-fb.o WARNING: modpost: missing MODULE_DESCRIPTION() in samples/vfio-mdev/mbochs.o Add the missing invocations of the MODULE_DESCRIPTION() macro to these modules. And in the case of mtty.c, remove the now redundant instance of the MODULE_INFO() macro.
