When the kernel is compiled with the sparse static analysis tool enabled, the following warnings are emitted: drivers/soc/qcom//trace_secure_buffer.h:53:1: warning: incorrect type in assignment (different base types) drivers/soc/qcom//trace_secure_buffer.h:53:1: warning: incorrect type in assignment (different base types) drivers/soc/qcom//trace_secure_buffer.h:53:1: warning: invalid assignment: += Fix this by converting the type of the addrs variable from phys_addr_t to u64, since the value we read into it is of type__le64 will always be 64 bits, while phys_addr_t may not be. Also, use the correct accessors when accessing variables of type __le64. Change-Id: Ia7e2394f2dc501dbf80f9035e0177555449dcfd8 Signed-off-by: Isaac J. Manjarres <isaacm@codeaurora.org>
