power/reset: arm-versatile: Fix refcount leak in versatile_reboot_probe

2022-07-29T15:10:31+00:00

[ Upstream commit 80192eff64eee9b3bc0594a47381937b94b9d65a ]

of_find_matching_node_and_match() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

power: reset: gemini-poweroff: Fix IRQ check in gemini_poweroff_probe

2022-04-15T12:14:47+00:00

[ Upstream commit ba18dad0fb880cd29aa97b6b75560ef14d1061ba ]

platform_get_irq() returns negative error number instead 0 on failure.
And the doc of platform_get_irq() provides a usage example:

    int irq = platform_get_irq(pdev, 0);
    if (irq < 0)
        return irq;

Fix the check of return value to catch errors correctly.

power: reset: ltc2952: Fix use of floating point literals

2022-01-11T12:58:50+00:00

commit 644106cdb89844be2496b21175b7c0c2e0fab381 upstream.

A new commit in LLVM causes an error on the use of 'long double' when
'-mno-x87' is used, which the kernel does through an alias,
'-mno-80387' (see the LLVM commit below for more details around why it
does this).

drivers/power/reset/ltc2952-poweroff.c:162:28: error: expression requires  'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it
        data->wde_interval = 300L * 1E6L;
                                  ^
drivers/power/reset/ltc2952-poweroff.c:162:21: error: expression requires  'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it
        data->wde_interval = 300L * 1E6L;
                           ^
drivers/power/reset/ltc2952-poweroff.c:163:41: error: expression requires  'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it
        data->trigger_delay = ktime_set(2, 500L*1E6L);
                                               ^
3 errors generated.

This happens due to the use of a 'long double' literal. The 'E6' part of
'1E6L' causes the literal to be a 'double' then the 'L' suffix promotes
it to 'long double'.

There is no visible reason for floating point values in this driver, as
the values are only assigned to integer types. Use NSEC_PER_MSEC, which
is the same integer value as '1E6L', to avoid changing functionality but
fix the error.

power: reset: gpio-poweroff: add missing MODULE_DEVICE_TABLE

2021-07-20T14:16:10+00:00

[ Upstream commit ed3443fb4df4e140a22f65144546c8a8e1e27f4e ]

This patch adds missing MODULE_DEVICE_TABLE definition which generates
correct modalias for automatic loading of this driver when it is built
as an external module.

power: vexpress: add suppress_bind_attrs to true

2020-06-22T07:05:27+00:00

commit 73174acc9c75960af2daa7dcbdb9781fc0d135cb upstream.

Make sure that the POWER_RESET_VEXPRESS driver won't have bind/unbind
attributes available via the sysfs, so lets be explicit here and use
".suppress_bind_attrs = true" to prevent userspace from doing something
silly.

treewide: convert ISO_8859-1 text comments to utf-8

2018-08-24T01:48:43+00:00

Almost all files in the kernel are either plain text or UTF-8 encoded.  A
couple however are ISO_8859-1, usually just a few characters in a C
comments, for historic reasons.

This converts them all to UTF-8 for consistency.
