Marijn Suijten 19526d092c opp: core: Check for pending links before reading required_opp pointers ... Commit 4fa82a87ba ("opp: Allow required-opps to be used for non genpd use cases") dereferences the pointers in required_opp_tables but these might be set to an ERR_PTR if the list still has lazy links pending, resulting in segfaults. Prior to this patch IS_ERR was also checked on required_opp_tables[i] before reading ->is_genpd inside _opp_table_alloc_required_tables, which is at the same time the predicate to add this table to the lazy list. This segfault is solved by reordering the checks to bail on lazy pending tables before reading ->is_genpd.
