We're seeing the already reported problem with the unused variable 'rpm', but also seeing this on Arm, i386, MIPS, PA-RISC:

| /builds/linux/drivers/pwm/pwm-tegra.c: In function 'tegra_pwm_config':
| /builds/linux/drivers/pwm/pwm-tegra.c:148:53: error: result of '1000000000 << 8' requires 39 bits to represent, but 'long int' only has 32 bits [-Werror=shift-overflow=]

| cc1: all warnings being treated as errors

Those are with GCC-8 and allmodconfig.
