These set of patches make some cleanup in some of the driver's functions.
The first patch changes the variables declaration, the second changes
the error checking logic and the third simply fixes a typo found while
making these changes.
Changes since v1:
- Small changes to patch 01 acording to Darren's comments
- Added a missing return on *eco_mode_available function
Azael Avalos (3):
toshiba_acpi: Clean up variable declaration
toshiba_acpi: Change error checking logic from TCI functions
toshiba_acpi: Fix typo in *_cooling_method_set function

This patch moves all the multiple line variable declaration to a
single line declaration (except variables being initialized)
following the reverse tree order, to conform to the practices
of the kernel.

Currently the success/error checking logic is intermixed, making the
code a bit cumbersome to understand.
This patch changes the affected functions to first check for errors
and take appropriate actions, then check for the supported features.
This patch also separates the error check from the acpi_status and
the tci_raw function call error check, as those two are completely
unrelated and were nested in if/else statements.

This is not consistent with the stated changes in the changelog, u32 mode is
longer than int ret, and should come before.

So, what I've done is fixed the last three instances, and queued this to
