hpet: Fix missing '=' character in the __setup() code of hpet_mmap_enable

Browse source

Commit '3d035f5806 ("drivers/char/hpet.c: allow user controlled mmap for
user processes")' introduced a new kernel command line parameter hpet_mmap,
that is required to expose the memory map of the HPET registers to
user-space. Unfortunately the kernel command line parameter 'hpet_mmap' is
broken and never takes effect due to missing '=' character in the __setup()
code of hpet_mmap_enable.

Before this patch:

dmesg output with the kernel command line parameter hpet_mmap=1

[    0.204152] HPET mmap disabled

dmesg output with the kernel command line parameter hpet_mmap=0

[    0.204192] HPET mmap disabled

After this patch:

dmesg output with the kernel command line parameter hpet_mmap=1

[    0.203945] HPET mmap enabled

dmesg output with the kernel command line parameter hpet_mmap=0

[    0.204652] HPET mmap disabled
