The local variable 'i' is initialized with -EINVAL, but the for loop
immediately overwrites it and -EINVAL is never returned.
If no empty compression mode can be found, the function would return the
out-of-bounds index IAA_COMP_MODES_MAX, which would cause an invalid

OTX_CPT_UCODE_NAME_LENGTH limits the microcode name to 64 bytes. If a
user writes a string of exactly 64 characters, the original code used
'strlen(buf) > 64' to check the length, but then strscpy() copies only
63 characters before adding a NUL terminator, silently truncating the
copied string.

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
