Subject: [PATCH v4 0/5] Introduce a new helper macro DEFINE_SHOW_STORE_ATTRIBUTE at seq_file.c

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 macro
for read-write file too.

So we add this macro to help decrease code duplication.

---
 v1->v2:
        1.Rename DEFINE_STORE_ATTRIBUTE() to DEFINE_SHOW_STORE_ATTRIBUTE().
	2.AI Viro points out that he doesn't like the definition of macros
	  like DEFINE_SHOW_ATTRIBUTE.
 v2->v3:
        1.Fixed some spelling mistakes in commit.
        2.Revision description are added for easy tracing.

 v3->v4:
	1.Add AI Viro's comment to v1->v2's revision description.
	2.Fixed a spelling mistakes of "marco" to "macro".
