Merge branch 'topic/kbuild-fixes-for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media build fixes from Mauro Carvalho Chehab: "A series of patches that fix compilation on non-x86 archs. While most of them are just build fixes, there are some fixes for real bugs, as there are a number of drivers using dynamic stack allocation. A few of those might be considered a security risk, if the i2c-dev module is loaded, as someone could be sending very long I2C data that could potentially overflow the Kernel stack. Ok, as using /dev/i2c-* devnodes usually requires root on usual distros, and exploiting it would require a DVB board or USB stick, the risk is not high" * 'topic/kbuild-fixes-for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (28 commits) [media] platform drivers: Fix build on frv arch [media] lirc_zilog: Don't use dynamic static allocation [media] mxl111sf: Don't use dynamic static allocation [media] af9035: Don't use dynamic static allocation [media] af9015: Don't use dynamic static allocation [media] dw2102: Don't use dynamic static allocation [media] dibusb-common: Don't use dynamic static allocation [media] cxusb: Don't use dynamic static allocation [media] v4l2-async: Don't use dynamic static allocation [media] cimax2: Don't use dynamic static allocation [media] tuner-xc2028: Don't use dynamic static allocation [media] tuners: Don't use dynamic static allocation [media] av7110_hw: Don't use dynamic static allocation [media] stv090x: Don't use dynamic static allocation [media] stv0367: Don't use dynamic static allocation [media] stb0899_drv: Don't use dynamic static allocation [media] dvb-frontends: Don't use dynamic static allocation [media] dvb-frontends: Don't use dynamic static allocation [media] s5h1420: Don't use dynamic static allocation [media] uvc/lirc_serial: Fix some warnings on parisc arch ...
