dfu: dfu_get_buf: check the value of env dfu_bufsiz before use
In function dfu_get_buf(), the size of allocated buffer could be defined by the env variable. The size from this variable was passed for memalign() without checking its value. And the the memalign will return non null pointer for size 0. This could possibly cause data abort, so now the value of var is checked before use. And if this variable is set to 0 then the default size will be used. This commit also changes the base passed to simple_strtoul() to 0. Now decimal and hex values can be used for the variable dfu_bufsiz. Signed-off-by: Przemyslaw Marczak <> Tested-by: Lukasz Majewski <> [TestHW: Exynos4412-Trats2]
