Input: ipaq-micro-keys - add error handling for devm_kmemdup
[ Upstream commit59b6a747e2
] Check the return value of i2c_add_adapter. Static analysis revealed that the function did not properly handle potential failures of i2c_add_adapter, which could lead to partial initialization of the I2C adapter and unstable operation.
