Subject: [PATCH v2 2/2] iio: adc: rzg2l_adc: Remove unnecessary channel check from rzg2l_adc_read_label()
Date: Thu,  5 May 2022 19:40:37 +0100	[thread overview]
Message-ID: <20220505184037.511295-3-biju.das.jz@bp.renesas.com> (raw)
In-Reply-To: <20220505184037.511295-1-biju.das.jz@bp.renesas.com>

Remove unnecessary channel check from rzg2l_adc_read_label(), as the channel error
handling is already done in probe(). Therefore no need to validate at runtime.
