Description
A flaw was found in the Linux kernel's microchip-core-qspi driver. When multiple devices are connected to the QSPI controller, the built-in chip select (CS) was automatically set to an active state even when Linux attempted to access a device using a General Purpose Input/Output (GPIO) pin for its chip select. This incorrect chip select behavior could lead to unexpected device interactions or operational issues.
