[PATCH 6.6 084/156] Input: ipaq-micro-keys - add error handling for devm_kmemdup

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Haoran Liu <liuhaoran14@xxxxxxx>

[ Upstream commit 59b6a747e2d39227ac2325c5e29d6ab3bb070c2a ]

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.
