Memory leak in libcups.so.2

[chandrakant2023]

Found the memory leak in libcups.so.2, following is the stack from the valgrind,
Any fix is available for Rocky 8 ?

==1065== 789,696 bytes in 3,656 blocks are definitely lost in loss record 18,029 of 18,033

Hi Team,
I found the way to mitigate the above stack --
in cups/dest.c in static int cups_enum_dests( ..)
where you return() add free(data.devices)
as you data.devices point to the allocated memory by cupsArrayNew3(..) which we need to free
