Hi all,

After merging the akpm tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/hwmon/dell-smm-hwmon.c: In function 'i8k_ioctl':
drivers/hwmon/dell-smm-hwmon.c:454:31: error: implicit declaration of function 'PDE_DATA'; did you mean 'NODE_DATA'? [-Werror=implicit-function-declaration]
454 | struct dell_smm_data *data = PDE_DATA(file_inode(fp));
| ^~~~~~~~
| NODE_DATA
drivers/hwmon/dell-smm-hwmon.c:454:31: error: initialization of 'struct dell_smm_data *' from 'int' makes pointer from integer without a cast [-Werror=int-conversion]
cc1: all warnings being treated as errors

Caused by commit

2dd082773083 ("proc: remove PDE_DATA() completely")

interacting with commit

073bd07205af ("hwmon: (dell-smm) Unify i8k_ioctl() and i8k_ioctl_unlocked()")

from the hwmon-staging tree.

I applied the following fixup patch.
