Sadly this has not seen much testing:

  CC      drivers/platform/x86/toshiba_haps.o
drivers/platform/x86/toshiba_haps.c: In function ‘toshiba_haps_resume’:
drivers/platform/x86/toshiba_haps.c:247:13: error: variable ‘ret’ set but not used [-Werror=unused-but-set-variable]
  247 |         int ret;
      |             ^~~
cc1: all warnings being treated as errors
make[5]: *** [scripts/Makefile.build:289: 
drivers/platform/x86/toshiba_haps.o] Error 1

...I guess you never took the time to look at and understand the 
surrounding code either. :-(
