-This reverts commit 7e5d1fd75c3dde9fc10c4472b9368089d1b81d00 ("pwm: Set
-class for exported channels in sysfs") as it causes regression with
-multiple pwm chip[1], when exporting a pwm channel (echo X > export):
-
-- ABI (Documentation/ABI/testing/sysfs-class-pwm) states pwmX should be
-  created in /sys/class/pwm/pwmchipN/pwmX
-- Reverted patch causes new entry to be also created directly in
-  /sys/class/pwm/pwmX
-- 1st time, exporting pwmX will create an entry in /sys/class/pwm/pwmX
-- class attributes are added under pwmX folder, such as export, unexport
-  npwm, symlinks. This is wrong as it belongs to pwmchipN. It may cause
-  bad behavior and report wrong values.
-- when another export happens on another pwmchip, it can't be created
-  (e.g. -EEXIST). This is causing the issue with multiple pwmchip.
-
-Example on stm32 (stm32429i-eval) platform:
-$ ls /sys/class/pwm
-pwmchip0 pwmchip4
-
-$ cd /sys/class/pwm/pwmchip0/
-$ echo 0 > export
-$ ls /sys/class/pwm
-pwm0 pwmchip0 pwmchip4
-
-$ cd /sys/class/pwm/pwmchip4/
-$ echo 0 > export
-sysfs: cannot create duplicate filename '/class/pwm/pwm0'
-...Exception stack follows...
-
-This is also seen on other platform [2]
