2013-08-07media: video: tegra: fix miscdevice registeration nametegra-l4t-r17.1tegra-l4t-r17-17r1Shreshtha Sahu
Allocate driver name string in info struct, rather than passing a pointer to a stack allocated array when registering a miscdevice. This prevents 'cat /proc/misc' from dereferencing a dangling pointer. Drivers of following devices were updated - ad5816, as364x, dw9718, imx091, max77387, max77665-flash, ov5693, ov9772, sh532u, ssl3250a and tps61050.
