This patch fixes several issues: - if the 1st 'kzalloc' fails, we dereference a NULL pointer - if the 2nd 'kzalloc' fails, there is a memory leak - if 'sysfs_create_bin_file' fails there is also a memory leak Fix it by adding a test after the first memory allocation and some error handling paths to correctly free memory if needed.
