4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bartlomiej Zolnierkiewicz b.zolnierkie@samsung.com
[ Upstream commit 719736e1cc12b2fc28eba2122893a449eee66d08 ]
'default n' is the default value for any bool or tristate Kconfig setting so there is no need to write it explicitly.
Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO is not set' for visible symbols") the Kconfig behavior is the same regardless of 'default n' being present or not:
... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same:
config FOO bool
config FOO bool default n
With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ...
