Hi all, After merging the opp tree, today's linux-next build (x86_64 allmodconfig) failed like this: x86_64-linux-gnu-ld: drivers/opp/core.o: in function `dev_pm_opp_put_opp_table': (.text+0x76e): undefined reference to `icc_put' x86_64-linux-gnu-ld: drivers/opp/core.o: in function `dev_pm_opp_set_rate': (.text+0x2c59): undefined reference to `icc_set_bw' x86_64-linux-gnu-ld: drivers/opp/of.o: in function `dev_pm_opp_of_find_icc_paths': (.text+0x3ca): undefined reference to `of_icc_get_by_index' x86_64-linux-gnu-ld: (.text+0x441): undefined reference to `icc_set_tag' x86_64-linux-gnu-ld: (.text+0x542): undefined reference to `icc_put' Caused by commit 12fa389dcf86 ("OPP: Add support for parsing interconnect bandwidth") I have used the opp tree from next-20200512 for today. -- Cheers, Stephen Rothwell
