From: Alex Dewar Date: Thu, 10 Sep 2020 13:49:10 +0000 (+0100) Subject: net: mvpp2: ptp: Fix unused variables X-Git-Tag: io_uring-5.10-2020-10-20~32^2~314 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=cdd0a379a6a3f7583ba6eedeef7c522aa4b2c5b3;p=linux-block.git net: mvpp2: ptp: Fix unused variables In the functions mvpp2_isr_handle_xlg() and mvpp2_isr_handle_gmac_internal(), the bool variable link is assigned a true value in the case that a given bit of val is set. However, if the bit is unset, no value is assigned to link and it is then passed to mvpp2_isr_handle_link() without being initialised. Fix by assigning to link the value of the bit test. Build-tested on x86. Fixes: 36cfd3a6e52b ("net: mvpp2: restructure "link status" interrupt handling") Signed-off-by: Alex Dewar Signed-off-by: David S.
