stable inclusion from stable-v5.10.137 commit 56924fc19d31d39107c15d7196730779ca9b35b4 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I60PLB
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 83781f0162d080fec7dcb911afd1bc2f5ad04471 ]
If an error occurs after a successful call to p54spi_request_firmware(), it must be undone by a corresponding release_firmware() as already done in the error handling path of p54spi_request_firmware() and in the .remove() function.
Add the missing call in the error handling path and remove it from p54spi_request_firmware() now that it is the responsibility of the caller to release the firmware
