ni_patch_single_dependency_table_based_on_leakage() return zero or
negative error code. But ni_patch_dependency_tables_based_on_leakage()
doesn't check the return value of the first function call. It's same for
ni_dpm_init(). It's better to add this error code check.

As Dan Carpenter mentioned:

prior to 2003. But these days it feels strange and dangerous to see

Sorry for that, I will split it and send
