commit ce676638fe7b284132a7d7d5e7e7ad81bab9947e upstream.

This also gets rid of two build warnings:

protection_keys.c: In function ‘dumpit’:
protection_keys.c:419:3: warning: ignoring return value of ‘write’, declared with attribute warn_unused_result [-Wunused-result]

     write(1, buf, nr_read);
     ^~~~~~~~~~~~~~~~~~~~~~
