Makefile for compiling each c source file into a Linux kernel module

I have a directory full of c source files, each one could be compiled into a independent kernel module, the following Makefile doesn't work:

sources := $(wildcard *.c)
obj-m += $(patsubst %.c,%.o,$(sources))

all:
    make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules

clean:
    make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

But if I use obj-m += mod1.o mod2.o this will work.

You can use the below snippet from makefile

obj-m += $(subst .c,.o, $(wildcard *.c))

subst will replace .c suffixes with .o

obj-m += $(sources:.c=.o)
