Linux kernel predating 6.4 (specifically commit 7cfb35d3a800 ("media: rkisp1: Implement ENUM_FRAMESIZES") do not have the ioctl in rkisp1 driver required to dynamically query the resizer limits. Because of that, maxResolution and minResolution are both {0, 0} (default value for Size objects) which means filterSensorResolution() will create an entry for the sensor in sensorSizesMap_ but because the sensor resolution cannot fit inside the min and max resolution of the rkisp1, no size is put into this entry in sensorSizesMap_. On the next call to filterSensorResolution(), sensorSizesMap_.find(sensor) will return the entry but when attempting to call back() on iter->second, it'll trigger an assert because the size array is empty. Linux kernel 6.1 is supported until December 2027, so it seems premature to get rid of those hard-coded resizer limits before this happens. Let's keep the hard-coded resizer limits by default, they can still be queried if necessary.
