[ Upstream commit 7c8881b77908a51814a050da408c89f1a25b7fb7 ]
A memory chunk was allocated for orom_data in ice_get_orom_civd_data() by vzmalloc(). But when ice_read_flash_module() fails, the allocated memory is not freed, which will lead to a memory leak.
We can fix it by freeing the orom_data when ce_read_flash_module() fails.
