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

Sorry, I should add a commit for the change.


In v1, Andy pointed out that the old name of DEFINE_STORE_ATTRIBUTE was 
easily misunderstood as a write-only file rather than a read-write file.

Therefore, it is changed to DEFINE_SHOW_STORE_ATTRIBUTE according to his 
suggestion.


Thanks

Jiaxing

All of that needs to go in the patch, below the --- line, or in the
00/XX email here, like is documented.

Please fix that up and resend a v3 if you wish for people to look at
this series and know what is going on.

thanks,
