[PATCH v2 0/5] Introduce a new helper marco DEFINE_SHOW_STORE_ATTRIBUTE at seq_file.c

[Luo Jiaxing <luojiaxing@xxxxxxxxxx>]

We already own DEFINE_SHOW_ATTRIBUTE() helper macro for defining attribute
for read-only file, but we found many of drivers also want a helper marco for
read-write file too.

So we try to add this macro to help decrease code duplication.

Luo Jiaxing (5):
  seq_file: Introduce DEFINE_SHOW_STORE_ATTRIBUTE() helper macro
  scsi: hisi_sas: Introduce DEFINE_SHOW_STORE_ATTRIBUTE for debugfs
  scsi: qla2xxx: Introduce DEFINE_SHOW_STORE_ATTRIBUTE for debugfs
  usb: dwc3: debugfs: Introduce DEFINE_SHOW_STORE_ATTRIBUTE
  drm/i915/display: Introduce DEFINE_SHOW_STORE_ATTRIBUTE for debugfs
