Subject: [PATCH AUTOSEL 5.12 12/33] spi: spi-zynq-qspi: Fix some wrong goto jumps & missing error code
Date: Tue, 15 Jun 2021 11:48:03 -0400 [thread overview]
Message-ID: <20210615154824.62044-12-sashal@kernel.org> (raw)
In-Reply-To: <20210615154824.62044-1-sashal@kernel.org>
From: zpershuai <zpershuai@gmail.com>
[ Upstream commit f131767eefc47de2f8afb7950cdea78397997d66 ]
In zynq_qspi_probe function, when enable the device clock is done,
the return of all the functions should goto the clk_dis_all label.
If num_cs is not right then this should return a negative error
code but currently it returns success.
