[PATCH] platform/x86: hp-bioscfg: Removed needless asm-generic

[Tanzir Hasan]

asm-generic/posix-types.h is obtained through bioscfg.h so there is no
need to include it. It is also an asm-generic file which should be
avoided if possible.

I verified that by:
1. building with V=1
2. taking the compiler invocation and adding -H

. drivers/platform/x86/hp/hp-bioscfg/bioscfg.h
.. ./include/linux/wmi.h
... ./include/linux/device.h
.... ./include/linux/dev_printk.h
..... ./include/linux/compiler.h
...... ./arch/x86/include/generated/asm/rwonce.h
....... ./include/asm-generic/rwonce.h
........ ./include/linux/kasan-checks.h
......... ./include/linux/types.h
.......... ./include/uapi/linux/types.h
........... ./arch/x86/include/generated/uapi/asm/types.h

............. ./arch/x86/include/uapi/asm/posix_types_64.h
.............. ./include/uapi/asm-generic/posix_types.h

Correct, though there is a linux/posix_types.h file.

biocfg.h hasn't seen any changes since introduction; perhaps some reference was
removed in follow up changes to passwdobj-attributes.c, but nothing stood out.

Regardless, this file builds just fine without either (asm/posix_types.h or
linux/posix_types.h), and asm-generic should not be used (as suggested by Al).

Thank you both for the patch + review, I've applied this patch to my
review-hans  branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans

Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.

Regards,

Hans
