[PATCH 6.12 5/7] slab: recognize @GFP parameter as optional in kernel-doc

From: Randy Dunlap <[email protected]>

commit 7b5f5865fb11e60edd03c5e063e2d228b7062317 upstream.

Since the @GFP parameter in kmalloc_obj() etc. is now optional, change
the kernel-doc to indicate that it is optional. This avoids kernel-doc
warnings:

WARNING: include/linux/slab.h:1101 Excess function parameter 'GFP' description in 'kmalloc_obj'
WARNING: include/linux/slab.h:1113 Excess function parameter 'GFP' description in 'kmalloc_objs'
WARNING: include/linux/slab.h:1128 Excess function parameter 'GFP' description in 'kmalloc_flex'

Fixes: e19e1b480ac7 ("add default_gfp() helper macro and use it in the new *alloc_obj() helpers")
