Subsystem:
emulex/broadcom lpfc fc/fcoe scsi driver, ibm power sriov virtual nic device driver, input (keyboard, mouse, joystick, touchscreen) drivers, linux for powerpc (32-bit and 64-bit), networking drivers, s390 architecture, scsi subsystem, the rest, thermal, x86 architecture (32-bit and 64-bit), x86 microcode update support · Maintainers:
Justin Tee, Paul Ely, Haren Myneni, Rick Lindsley, Dmitry Torokhov, Madhavan Srinivasan, Michael Ellerman, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Heiko Carstens, Vasily Gorbik, Alexander Gordeev, "James E.J. Bottomley", "Martin K. Petersen", Linus Torvalds, Rafael J. Wysocki, Daniel Lezcano, Thomas Gleixner, Ingo Molnar, Borislav Petkov, Dave Hansen
Convert DEVICE_ATTR uses to DEVICE_ATTR_WO where possible.
Done with perl script:
$ git grep -w --name-only DEVICE_ATTR | \
xargs perl -i -e 'local $/; while (<>) { s/\bDEVICE_ATTR\s*\(\s*(\w+)\s*,\s*\(?(?:\s*S_IWUSR\s*|\s*0200\s*)\)?\s*,\s*NULL\s*,\s*\s_store\s*\)/DEVICE_ATTR_WO(\1)/g; print;}'
