Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/trivial
Pull trivial tree from Jiri Kosina: "It's indeed trivial -- mostly documentation updates and a bunch of typo fixes from Masanari. There are also several linux/version.h include removals from Jesper." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/trivial: (101 commits) kcore: fix spelling in read_kcore() comment constify struct pci_dev * in obvious cases Revert "char: Fix typo in viotape.c" init: fix wording error in mm_init comment usb: gadget: Kconfig: fix typo for 'different' Revert "power, max8998: Include linux/module.h just once in drivers/power/max8998_charger.c" writeback: fix fn name in writeback_inodes_sb_nr_if_idle() comment header writeback: fix typo in the writeback_control comment Documentation: Fix multiple typo in Documentation tpm_tis: fix tis_lock with respect to RCU Revert "media: Fix typo in mixer_drv.c and hdmi_drv.c" Doc: Update numastat.txt qla4xxx: Add missing spaces to error messages compiler.h: Fix typo security: struct security_operations kerneldoc fix Documentation: broken URL in libata.tmpl Documentation: broken URL in filesystems.tmpl mtd: simplify return logic in do_map_probe() mm: fix comment typo of truncate_inode_pages_range power: bq27x00: Fix typos in comment ...
