+Subject: [PATCH] core: pass VIDIOC_QUERYCAP as unsigned long
+
+VIDIOC_QUARYCAP is an unsigned long and should be passed as one.
+
+Get rid of the following error:
+core/libcamera_app.cpp:33:22: error: overflow in conversion from 'long unsigned int' to 'int' changes value from '2154321408' to '-2140645888' [-Werror=overflow]
+ 33 | int ret = ioctl(fd, VIDIOC_QUERYCAP, &caps);
