* spi: Correct two error return valuesSimon Glass2016-02-26-4/+2
| | | | | | | | | | | | | When an error number is provided we should use it, not change it. This fixes the SPI and SPI flash tests. One of these is long-standing. The other seems to have been introduced by commit 1e90d9fd (sf: Move read_id code to sf_ops).

* sandbox: spi: Remove an incorrect free()Simon Glass2016-02-26-1/+0
| | | | | | | | | | | | | We must not free data that is managed by driver mode. Remove this line, which is a hangover from the pre-driver-model code. This fixes a problem where 'sf probe' crashes U-Boot if the backing file for the SPI flash cannot be found.

|/ | | | | | | | | | | | | | | | BUILD_BUG_* macros have been defined in several headers. It would be nice to collect them in include/linux/bug.h like Linux. This commit is cherry-picking useful macros from include/linux/bug.h of Linux 4.4. I did not import BUILD_BUG_ON_MSG() because it would not work if it is used with include/common.h in U-Boot. I'd like to postpone it until the root cause (the "error()" macro in include/common.h causes the name conflict with "__attribute__((error()))") is fixed.
