A bunch of GPIO fixes for the v4.7 series:
- Drop the lock before reading out the GPIO direction setting in drivers supporting the .get_direction() callback: some of them may be slowpath. - Flush GPIO direction setting before locking a GPIO as an IRQ: some electronics or other poking around in the registers behind our back may have happened, so flush the direction status before trying to lock the line for use by IRQs. - Bail out silently when asked to perform operations on NULL GPIO descriptors. That is what all the get_*_optional() is about: we get optional GPIO handles, if they are not there, we get NULL. - Handle compatible ioctl() correctly: we need to convert the ioctl() pointer using compat_ptr() here like everyone else. - Disable the broken .to_irq() on the LPC32xx platform. The whole irqchip infrastructure was replaced in the last merge window, and a new implementation will be needed. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJXTTtPAAoJEEEQszewGV1zOEIP/AuYXFdcjFDxHbx+DWdObNSh XKvpbRliFDyjyGy/omXCUQg0tl0/2SD1wm+I8kMwfKRwmN1S8bt5wIrVEIOOHTwC lZgj16qzJwS0exmAfRQ5ooQEmF3W8ZcN6aUOMlUy/uwgk8t0wbQPUChT9lSURgMw qsGnL3ci0QnVbgCngAR6h964LAHYttyOa1scBD6naVQwgrO8g4ad/KiC38vu2z/d eFsfrX8A5q9w/TS6Zz+Ue7RBBiZb4XRJ5dNsfgS4+W940NDCMq1F73cmE90Hzzs/ 4Lx+56Y5cXJn8C90DM1kU/uVfdXU0XPA9R8CC4lT4sO6HSkWEW1ZcOrMpNXshJfZ DR5h4W03WSD+QT6lZIt0kIo3xFWE/5HFS5xLLPPm2dOnNgwUSru7v0x82RWyClLl NOVcxJ7rsgUXLc4J+zi+r+Lhtb+2cMuwt2PS8QISeSzYcSSOXmiqRrMsO0SKsr0h JnEaCvC08Utm1RalATelmtoM4eIYl6kuODX14xdOI8hsvrSKeUF5cekzot6ivHO3 /w286hovt102j51F3wMxRuAOmL5S3GuoypQBiNNDOQhkyMLtuzcjfz//38RW5Ooo CtoNbL59BnpR4zYT0Xdm5zPTHohJdC1B6/mANCuWZJM40IQ5VVoeJXEshdJ2YQe/ U5m25QNqer2Xm4GJYfGh =5IlZ -----END PGP SIGNATURE-----
