4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Boris Brezillon boris.brezillon@bootlin.com
commit 49012d1bf5f78782d398adb984a080a88ba42965 upstream.
ana->maskX values are already '~'-ed in bcm2835_pll_set_rate(). Remove the '~' in the definition to fix ANA setup.
Note that this commit fixes a long standing bug preventing one from using an HDMI display if it's plugged after the FW has booted Linux. This is because PLLH is used by the HDMI encoder to generate the pixel clock.
