Marti Bolivar 3ac9ca0859 spi: dw: fix spi_dw_init() ... It is incorrect to call spi_context_release() on a spi_dw_data object's ctx field before data->ctx->config is first set in spi_dw_configure(). This is because spi_context_release() reads ctx->config->operation. In particular, during spi_dw_init(), calling spi_context_release() reads the uninitialized memory in spi->ctx->config->operation. Call spi_context_unlock_unconditionally() instead to properly increase the semaphore count. Without this patch, the first call to spi_transceive() can block forever depending on the value of the uninitialized memory holding spi->ctx->config->operation.
