[PATCH 0/1] kernel: fix numerous spelling mistakes

[Zhen Lei]

These files are not organized by module(subdirectory), or even if they can, the
number of spelling mistakes is small and not worth generating a separate patch.

This patch is based on the latest linux-next. But except the modification of
kernel/delayacct.c, the remaining can also be applied on 5.13-rc3.

[PATCH 1/1] kernel: fix numerous spelling mistakes

[Zhen Lei]

Fix some spelling mistakes in comments:
suspeneded ==> suspended
occuring ==> occurring
wont ==> won't
detatch ==> detach
represntation ==> representation
hexidecimal ==> hexadecimal
delimeter ==> delimiter
architecure ==> architecture
accumalator ==> accumulator
evertything ==> everything
contingous ==> contiguous
useable ==> usable
musn't ==> mustn't
alloed ==> allowed
immmediately ==> immediately
Allocted ==> Allocated
noone ==> no one
unparseable ==> unparsable
dependend ==> dependent
callled ==> called
alreay ==> already
childs ==> children
implemention ==> implementation
situration ==> situation
overriden ==> overridden
asynchonous ==> asynchronous
accumalate ==> accumulate
syncrhonized ==> synchronized
therefor ==> therefore
ther ==> their
capabilites ==> capabilities
lentgh ==> length
watchog ==> watchdog
assing ==> assign
Retun ==> Return
