[Buildroot] [git commit] package/sunxi-mali-mainline-driver: fix build failure with Linux 5.9 and 5.10

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=6bb9cffebcca4dc39938321dd98472026ac46124
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Add 2 patches pending[1] upstream to fix build failure with both Linux 5.9
and Linux 5.10 due to uaccess.h file moved after version >= 5.9 and and
due to moved code from dma-contiguous.h to dma-mapping.

+Subject: [PATCH] mali: support building against 5.9
+
+Add patches to fix build failure with Linux version 5.9 due to
+asm/uaccess.h changes and HAVE_UNLOCKED_IOCTL macro missing in version
+r6p0 and r6p2. While for r8p1 and r9p0 patch is the same and is located
+in patches/ root and fix HAVE_UNLOCKED_IOCTL issue only.

++Starting from Linux version 5.10.0 <linux/dma-contiguous.h> has been

++to build failure with Linux 5.10. So let's include
