Errors while compiling => In jit.c

[zoe9216]

Was trying to make from directory ldd3. However, I got the following errors: In function ‘jit_fn_open’: /home/meraj_hasan/ldd3/misc-modules/jit.c:96:40: error: implicit declaration of function ‘PDE_DATA’; did you mean ‘NODE_DATA’? [-Werror=implicit-function-declaration] 96 | return single_open(file, jit_fn_show, PDE_DATA(inode)); | ^~~~~~~~ | NODE_DATA /home/meraj_hasan/ldd3/misc-modules/jit.c:96:40: error: passing argument 3 of ‘single_open’ makes pointer from integer without a cast [-Werror=int-conversion] 96 | return single_open(file, jit_fn_show, PDE_DATA(inode)); | ^~~~~~~~~~~~~~~ | | | int In file included from /home/meraj_hasan/ldd3/misc-modules/jit.c:26: ./include/linux/seq_file.h:166:68: note: expected ‘void *’ but argument is of type ‘int’ 166 | int single_open(struct file *, int (*)(struct seq_file *, void *), void *); | ^~~~~~ /home/meraj_hasan/ldd3/misc-modules/jit.c: In function ‘jit_tasklet_open’: /home/meraj_hasan/ldd3/misc-modules/jit.c:306:45: error: passing argument 3 of ‘single_open’ makes pointer from integer without a cast [-Werror=int-conversion] 306 | return single_open(file, jit_tasklet_show, PDE_DATA(inode)); | ^~~~~~~~~~~~~~~ | | | int In file included from /home/meraj_hasan/ldd3/misc-modules/jit.c:26: ./include/linux/seq_file.h:166:68: note: expected ‘void *’ but argument is of type ‘int’ 166 | int single_open(struct file *, int (*)(struct seq_file *, void *), void *); | ^~~~~~ cc1: all warnings being treated as errors make[3]: *** [scripts/Makefile.build:250: /home/meraj_hasan/ldd3/misc-modules/jit.o] Error 1 make[2]: *** [Makefile:1992: /home/meraj_hasan/ldd3/misc-modules] Error 2 make[2]: Leaving directory '/home/meraj_hasan/linux' make[1]: *** [Makefile:20: modules] Error 2 make[1]: Leaving directory '/home/meraj_hasan/ldd3/misc-modules' make: *** [Makefile:10: subdirs] Error 1

How do I fix these? Earlier I had to do make oldconfig and make prepare in linux directory as some files were missing.
