Subject: [PATCH] spi: pca2xx-pci: Fix an issue about missing call to 'pci_free_irq_vectors()'
Date:   Sun, 14 Feb 2021 22:57:46 +0800
Message-Id: <20210214145746.602770-1-zhengdejin5@gmail.com>

Precedence: bulk

Call to 'pci_free_irq_vectors()' are missing both in the error handling
path of the probe function, and in the remove function. So add them.

Fixes: 64e02cb0bdfc7c ("spi: pca2xx-pci: Allow MSI")
