Hi Jiri, Today's linux-next build (x86_64_allmodconfig) failed like this: drivers/mfd/ab3100-otp.c: In function 'show_otp': drivers/mfd/ab3100-otp.c:101: error: dereferencing pointer to incomplete type drivers/mfd/ab3100-otp.c:104: error: implicit declaration of function 'seq_printf' drivers/mfd/ab3100-otp.c:102: warning: unused variable 'err' drivers/mfd/ab3100-otp.c: In function 'ab3100_otp_open': drivers/mfd/ab3100-otp.c:116: error: implicit declaration of function 'single_open' drivers/mfd/ab3100-otp.c:116: error: 'ab3100_otp_show' undeclared (first use in this function) drivers/mfd/ab3100-otp.c: At top level: drivers/mfd/ab3100-otp.c:121: error: 'seq_read' undeclared here (not in a function) drivers/mfd/ab3100-otp.c:122: error: 'seq_lseek' undeclared here (not in a function) drivers/mfd/ab3100-otp.c:123: error: 'single_release' undeclared here (not in a function) drivers/mfd/ab3100-otp.c: In function 'ab3100_otp_init_debugfs': drivers/mfd/ab3100-otp.c:134: error: 'err' undeclared (first use in this function) drivers/mfd/ab3100-otp.c: In function 'ab3100_otp_exit_debugfs': drivers/mfd/ab3100-otp.c:140: error: implicit declaration of function 'debugfs_remove_file' Exposed by commit 8dcafdf0475eb4633401d1f0bf0e0d35e4ebb9d5 "CONFIG_DEBUG_FS wrongly written as CONFIG_DEBUGFS". I have reverted that commit for today. That file probably just needs to include <linux/seq_file.h> ... -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx http://www.canb.auug.org.au/~sfr/
