Description

In the Linux kernel, the following vulnerability has been resolved:EOL][EOL]i2c: qup: jump out of the loop in case of timeout[EOL][EOL]Original logic only sets the return value but doesn't jump out of the[EOL]loop if the bus is kept active by a client. This is not expected. A[EOL]malicious or buggy i2c client can hang the kernel in this case and[EOL]should be avoided. This is observed during a long time test with a[EOL]PCA953x GPIO extender.[EOL][EOL]Fix it by changing the logic to not only sets the return value, but also[EOL]jumps out of the loop and return to the caller with -ETIMEDOUT.
