4.17-stable review patch. If anyone has any objections, please let me know. ------------------ From: Anders Roxell <anders.roxell@xxxxxxxxxx> [ Upstream commit dd4b16b4f9b1b7d9f4a185cb8222e42f3a5daf00 ] We were picking up the wrong header should use asm/ioctls.h form the kernel and not the header from the system (sys/ioctl.h). In the current code we added the correct include and we added the kernel headers path to the CFLAGS.
