coccinelle: alloc_cast: drop removed allocatorsgrafted
- pci_alloc_consistent() and pci_zalloc_consistent() were removed by commit 7968778914e5 ("PCI: Remove the deprecated "pci-dma-compat.h" API") - kmem_alloc() was removed by commit f078d4ea8276 ("xfs: convert kmem_alloc() to kmalloc()") - kmem_zalloc() was removed by commit 10634530f7ba ("xfs: convert kmem_zalloc() to kzalloc()") - kmem_zone_alloc() and kmem_zone_zalloc() were removed by commit bae633a4a283 ("xfs: remove xfs_zone_{alloc,zalloc} helpers") So drop them from the rules. No functional change. Signed-off-by: Sang-Heon Jeon <ekffu200098@gmail.com> Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr>

+sm712fb - Silicon Motion SM712 graphics framebuffer driver
+==========================================================
+
+This is a graphics framebuffer driver for Silicon Motion SM712 based processors.
+
+How to use it?
+==============
+
+Switching modes is done using the video=sm712fb:... boot parameter.
+
+If you want, for example, enable a resolution of 1280x1024x24bpp you should
+pass to the kernel this command line: "video=sm712fb:0x31B".
+
+You should not compile-in vesafb.
+
+Currently supported video modes are:
