Merge tag 'staging-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging driver updates from Greg KH: "Here's the big, really big, staging tree patches for 4.2-rc1. Loads of stuff in here, almost all just coding style fixes / churn, and a few new drivers as well, one of which I just disabled from the build a few minutes ago due to way too many build warnings. Other than the one "disable this driver" patch, all of these have been in linux-next for quite a while with no reported issues" * tag 'staging-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (1163 commits) staging: wilc1000: disable driver due to build warnings Staging: rts5208: fix CHANGE_LINK_STATE value Staging: sm750fb: ddk750_swi2c.c: Insert spaces before parenthesis Staging: sm750fb: ddk750_swi2c.c: Place braces on correct lines Staging: sm750fb: ddk750_swi2c.c: Insert spaces around operators Staging: sm750fb: ddk750_swi2c.c: Replace spaces with tabs Staging: sm750fb: ddk750_swi2c.h: Shorten lines to under 80 characters Staging: sm750fb: ddk750_swi2c.h: Replace spaces with tabs Staging: sm750fb: modedb.h: Shorten lines to under 80 characters Staging: sm750fb: modedb.h: Replace spaces with tabs staging: comedi: addi_apci_3120: rename 'this_board' variables staging: comedi: addi_apci_1516: rename 'this_board' variables staging: comedi: ni_atmio: cleanup ni_getboardtype() staging: comedi: vmk80xx: sanity check context used to get the boardinfo staging: comedi: vmk80xx: rename 'boardinfo' variables staging: comedi: dt3000: rename 'this_board' variables staging: comedi: adv_pci_dio: rename 'this_board' variables staging: comedi: cb_pcidas64: rename 'thisboard' variables staging: comedi: cb_pcidas: rename 'thisboard' variables staging: comedi: me4000: rename 'thisboard' variables ...
