| |
In preparation to enabling -Wvla, remove VLA usage and replace it with fixed-length arrays.
It seems that the length of array 'buf' will not exceed DA9150_QIF_SHORT_SIZE bytes (2 bytes). But a fixed length of DA9150_QIF_BYTE_SIZE bytes (8 bytes) was chosen in case this change in the future.
Fixed as part of the directive to remove all VLAs from the kernel: https://lkml.org/lkml/2018/3/7/621
