|
||||
|
||||
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.

CM_PLLx and A2W_XOSC_CTRL registers are accessed by different clock
|

handlers and must be accessed with ->regs_lock held.
|
||||
Update the sections where this protection is missing.

Subject: [PATCH] floppy: Don't print kernel addresses to log in show_floppy
|
||||
|
||||
Outputting kernel addresses will reveal the locations of kernel code
|
||||
and data. Change the cases in show_floppy that print
|
||||
fd_timer.work.func and fd_timeout.work.func to use the %pf format
|
||||
specifier, which will print the symbol name, like what is done for the
|
||||
other function pointers printed by show_floppy. No longer output the
|
||||
value of cont. The variable cont is a pointer that can hold the
|
||||
address of kernel global variables.
