kmalloc on efuse_word can return null, leading to free'ing of elements in efuse_word on the error exit path even though it has not been allocated. Instead, don't free the elements of efuse_word if kmalloc failed. Also, kmalloc of any of the arrays in efuse_word[] can also fail, leading to undefined contents in the remaining elements leading to problems when free'ing these elements later on. So kzalloc efuse_word to ensure the kfree on the remaining elements won't cause breakage. Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: John W.
