[PROBLEM linux-next] drivers/mux/adg792a.c:134:34: error: ‘adg792a_of_match’ defined but not used [-Werror=unused-const-variable=]

[Mirsad Todorovac]

Dear all,

On the linux-next vanilla next-20240709 tree, I have attempted the seed KCONFIG_SEED=0xEE7AB52F
which was known from before to trigger various errors in compile and build process.

Though this might seem as contributing to channel noise, Linux refuses to build this config,
treating warnings as errors, using this build line:

$ time nice make W=1 -k -j 36 |& tee ../err-next-20230709-01a.log; date

As I know that the Chief Penguin doesn't like warnings, but I am also aware that there are plenty
left, there seems to be more tedious work ahead to make the compilers happy.

The compiler output is:

drivers/mux/adg792a.c:134:34: error: ‘adg792a_of_match’ defined but not used [-Werror=unused-const-variable=]
  134 | static const struct of_device_id adg792a_of_match[] = {
      |                                  ^~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors

The offending lines are:

drivers/mux/adg792a.c:134
134 static const struct of_device_id adg792a_of_match[] = {
135         { .compatible = "adi,adg792a", },
136         { .compatible = "adi,adg792g", },
137         { }
138 };
139 MODULE_DEVICE_TABLE(of, adg792a_of_match);

Hope this helps.

Best regards,
