drivers core: Miscellaneous changes for sysfs_emit

mainline inclusion
from mainline-v5.10-rc1
commit 948b3edb
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I5C32F


CVE: CVE-2022-20166

--------------------------------------------------

Change additional instances that could use sysfs_emit and sysfs_emit_at
that the coccinelle script could not convert.

o macros creating show functions with ## concatenation
o unbound sprintf uses with buf+len for start of output to sysfs_emit_at
o returns with ?: tests and sprintf to sysfs_emit
o sysfs output with struct class * not struct device * arguments

Miscellanea:

o remove unnecessary initializations around these changes
o consistently use int len for return length of show functions
o use octal permissions and not S_<FOO>
o rename a few show function names so DEVICE_ATTR_<FOO> can be used
o use DEVICE_ATTR_ADMIN_RO where appropriate
o consistently use const char *output for strings
o checkpatch/style neatening
