For my upcoming PCI device authentication v2 patches, I have the need to expose a simple buffer in virtual memory as a bin_attribute. It turns out we've duplicated the ->read() callback for such simple buffers a fair number of times across the tree. So instead of reinventing the wheel, I decided to introduce a common helper and eliminate all duplications I could find. I'm open to a bikeshedding discussion on the sysfs_bin_attr_simple_read() name. ;) Lukas Wunner (2): sysfs: Add sysfs_bin_attr_simple_read() helper treewide: Use sysfs_bin_attr_simple_read() helper arch/powerpc/platforms/powernv/opal.c | 10 +------- drivers/acpi/bgrt.c | 9 +------- drivers/firmware/dmi_scan.c | 12 ++-------- drivers/firmware/efi/rci2-table.c | 10 +------- drivers/gpu/drm/i915/gvt/firmware.c | 26 +++++---------------- .../intel/int340x_thermal/int3400_thermal.c | 9 +------- fs/sysfs/file.c | 27 ++++++++++++++++++++++ include/linux/sysfs.h | 15 ++++++++++++ init/initramfs.c | 10 +------- kernel/module/sysfs.c | 13 +---------- 10 files changed, 56 insertions(+), 85 deletions(-) -- 2.43.0
