fujitsu-laptop: fix error return code · b30bb89f

由 Julia Lawall 提交于 12月 29, 2013

These functions mix the use of result and error.  In acpi_fujitsu_add,
result does not seem useful; it would seem reasonable to propagate the
return value of acpi_bus_update_power in an error case.  On the other hand,
in the case of acpi_fujitsu_hotkey_add, there is an initialization of
result that can lead to what looks like a failure case, but that does not
abort the function.  The variable result is kept for this case.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}

// </smpl>

dell-laptop: Only install the i8042 filter when rfkill is active · 97f440c2

由 Hans de Goede 提交于 12月 24, 2013

Installing the i8042 filter is not useful on machines where rfkill is not
whitelisted, so move the filter installation into dell_setup_rfkill,
after the whitelist check.

This avoids doing a needless and potentially troublesome rfkill query
(dell_send_request(buf, 17, 11)) when the wireless Fn key gets pressed on
non whitelisted laptops.

This patch was written as a result of:
https://bugzilla.redhat.com/show_bug.cgi?id=1045807
It is not yet clear if this is related, but it is a good idea to not register
the i8042 filter in general.

X86 platform: New BayTrail IOSF-SB MBI driver · 997ab407

由 David E. Box 提交于 12月 19, 2013

Current Intel SOC cores use a MailBox Interface (MBI) to provide access to unit
devices connected to the system fabric. This driver implements access to this
interface on BayTrail platforms. This is a requirement for drivers that need
access to unit registers on the platform (e.g. accessing the PUNIT for power
management features such as RAPL). Serialized access is handled by all exported
routines with spinlocks.

The API includes 3 functions for access to unit registers:

int bt_mbi_read(u8 port, u8 opcode, u32 offset, u32 *mdr)
int bt_mbi_write(u8 port, u8 opcode, u32 offset, u32 mdr)
int bt_mbi_modify(u8 port, u8 opcode, u32 offset, u32 mdr, u32 mask)

port:	indicating the unit being accessed
opcode:	the read or write port specific opcode
offset:	the register offset within the port
mdr:	the register data to be read, written, or modified
mask:	bit locations in mdr to change

Returns nonzero on error

Note: GPU code handles access to the GFX unit. Therefore access to that unit
with this driver is disallowed to avoid conflicts.

drivers: platform: Include appropriate header file in mxm-wmi.c · 475879d6

由 Rashika Kheria 提交于 12月 13, 2013

This patch includes appropriate header file linux/mxm-wmi.h in
x86/mxm-wmi.c because functions mxm_wmi_call_mxds(), mxm_wmi_call_mxmx()
and mxm_wmi_supported() have their prototype declaration in
linux/mxm-wmi.h.

Thus, it also eliminates the following warnings in x86/mxm-wmi.c:
drivers/platform/x86/mxm-wmi.c:43:5: warning: no previous prototype for ‘mxm_wmi_call_mxds’ [-Wmissing-prototypes]

This patch marks the functions lis3lv02d_acpi_init(),
lis3lv02d_acpi_read() and lis3lv02d_acpi_write() as static in
x86/hp_accel.c because they are not used outside this file.

Thus, it also eliminates the following warnings in x86/hp_accel.c:
