my Makefile:

obj-m += qmi_wwan.o

CFLAGS += -Werror -Wno-implicit-function-declaration

all:
    make -C /lib/modules/5.10.103-v7l+/build M=$(PWD) modules
clean:
    make -C /lib/modules/5.10.103-v7l+/build M=$(PWD) clean

Error i get while compiling:

warning: implicit declaration of function ‘dev_sw_netstats_tx_add’; did you mean ‘dev_sw_netstats_rx_add’? [-Wimplicit-function-declaration]
warning: implicit declaration of function ‘dev_addr_mod’; did you mean ‘dev_addr_add’? [-Wimplicit-function-declaration]

Additional informations: I'm configuring qmi_wwan module to add Quectel RM520N as it was explained -> in this thread

Thanks in advance for any help.

Problem solved. I was compiling qmi_wwan from kernel 5.15.y on my current kernel 5.10.y, that's why i've got this error. After compiling qmi_wwan driver from 5.10.y, the problem dissapeared.
