hwmon: (sht15) Fix integer overflow in humidity calculation

2011-03-23T20:04:16+00:00

commit ccd32e735de7a941906e093f8dca924bb05c5794 upstream.

An integer overflow occurs in the calculation of RHlinear when the
relative humidity is greater than around 30%. The consequence is a subtle
(but noticeable) error in the resulting humidity measurement.

davinci: DM644x EVM: register MUSB device earlier

2011-03-23T20:04:15+00:00

commit 60d97a840175d3becb2e6de36537a5cdfc0ec3a9 upstream.

The MUSB driver doesn't see its platform device on DM644x EVM board anymore
since commit 73b089b052a69020b953312a624a6e1eb5b81fab (usb: musb: split davinci
to its own platform_driver) because the new probe is called as subsys_initcall()
now, and the device is registered later than that by the board code.  Move the
registration to davinci_evm_init() -- it's safe to do so because the MUSB core
device still gets initialized as fs_initcall() -- which is late enough for the
I2C GPIO expander (which controls VBUS) to be initialized.

x86, binutils, xen: Fix another wrong size directive

2011-03-23T20:04:14+00:00

commit 371c394af27ab7d1e58a66bc19d9f1f3ac1f67b4 upstream.

The latest binutils (2.21.0.20110302/Ubuntu) breaks the build
yet another time, under CONFIG_XEN=y due to a .size directive that
refers to a slightly differently named (hence, to the now very
strict and unforgiving assembler, non-existent) symbol.

[ mingo:

   This unnecessary build breakage caused by new binutils
   version 2.21 gets escallated back several kernel releases spanning
   several years of Linux history, affecting over 130,000 upstream
   kernel commits (!), on CONFIG_XEN=y 64-bit kernels (i.e. essentially
   affecting all major Linux distro kernel configs).

   Git annotate tells us that this slight debug symbol code mismatch
   bug has been introduced in 2008 in commit 3d75e1b8:

     3d75e1b8        (Jeremy Fitzhardinge    2008-07-08 15:06:49 -0700 1231) ENTRY(xen_do_hypervisor_callback)   # do_hypervisor_callback(struct *pt_regs)

   The 'bug' is just a slight assymetry in ENTRY()/END()
   debug-symbols sequences, with lots of assembly code between the
   ENTRY() and the END():

     ENTRY(xen_do_hypervisor_callback)   # do_hypervisor_callback(struct *pt_regs)
       ...
     END(do_hypervisor_callback)

   Human reviewers almost never catch such small mismatches, and binutils
   never even warned about it either.

   This new binutils version thus breaks the Xen build on all upstream kernels
   since v2.6.27, out of the blue.

   This makes a straightforward Git bisection of all 64-bit Xen-enabled kernels
   impossible on such binutils, for a bisection window of over hundred
   thousand historic commits. (!)

   This is a major fail on the side of binutils and binutils needs to turn
   this show-stopper build failure into a warning ASAP. ]

mmc: sdio: remember new card RCA when redetecting card

2011-03-23T20:04:12+00:00

commit 0aab3995485b8a994bf29a995a008c9ea4a28054 upstream.

During redetection of a SDIO card, a request for a new card RCA
was submitted to the card, but was then overwritten by the old RCA.
This caused the card to be deselected instead of selected when using
the incorrect RCA.  This bug's been present since the "oldcard"
handling was introduced in 2.6.32.

HID: Do not create input devices for feature reports

2011-03-23T20:04:09+00:00

commit f635bd11c8d332d917fb9a4cad3071b2357d5b2a upstream.

When the multi input quirk is set, there is a new input device
created for every feature report. Since the idea is to present
features per hid device, not per input device, revert back to
the original report loop and change the feature_mapping() callback
to not take the input device as argument.
