platform/x86: asus-wireless: Fix uninitialized symbol usage

2018-10-03T23:59:09Z

[ Upstream commit eca4c4e47eb0658ad251f0bff465e23c055377da ] 'ret' will not be initialized if acpi_evaluate_integer() returns through an error path, so it should not be used in this case. This fixes the following Smatch static analyser error: drivers/platform/x86/asus-wireless.c:76 asus_wireless_method() error: uninitialized symbol 'ret'.

platform/x86: ideapad-laptop: Apply no_hw_rfkill to Y20-15IKBM, too

2018-09-05T07:29:47Z

commit 58e73aa177850babb947555257fd4f79e5275cf1 upstream. The commit 5d9f40b56630 ("platform/x86: ideapad-laptop: Add Y520-15IKBN to no_hw_rfkill") added the entry for Y20-15IKBN, and it turned out that another variant, Y20-15IKBM, also requires the no_hw_rfkill. Trim the last letter from the string so that it matches to both Y20-15IKBN and Y20-15IKBM models.

platform/x86: wmi: Do not mix pages and kmalloc

2018-09-05T07:29:47Z

commit 6fb741076a9fc53355e56dff2e2b46782b3a46d3 upstream. The probe handler_data was being allocated with __get_free_pages() for no reason I could find. The error path was using kfree(). Since other things are happily using kmalloc() in the probe path, switch to kmalloc() entirely. This fixes the error path mismatch and will avoid issues with CONFIG_HARDENED_USERCOPY_PAGESPAN=y.

platform/x86: dell-laptop: Fix backlight detection

2018-07-20T12:29:59Z

Fix return code check for "max brightness" ACPI call. The Dell laptop ACPI video brightness control is not present on dell laptops anymore, but was present in older kernel versions. The code that checks the return value is incorrect since the SMM refactoring. The old code was: if (buffer->output[0] == 0) Which was changed to: ret = dell_send_request(...) if (ret) However, dell_send_request() will return 0 if buffer->output[0] == 0, so we must change the check to: if (ret == 0) This issue was found on a Dell M4800 laptop, and the fix tested on it as well.
